<p>The Parameter (PARM) command definition statement defines a parameter of a command being created. A parameter is the means by which a value is passed to the command processing program. One PARM statement must be used for each parameter that appears in the command being defined. The order in which the PARM statements are entered into the source file determines the order in which the parameters must be specified when the command is entered in positional form and the order in which they are passed to the validity checker and the command processing program. A maximum of 99 parameters can be defined for one command. A command with a large number of parameters will require more processing time before the command processing program is called, regardless of how many parameters are actually coded.
</p>
<p>
<b>Note: </b>The PARM statement contains certain parameters and predefined values that can be used only when IBM-supplied command processing programs are called by the command being defined. Because of limitations in some high-level languages, these values may not be useful in the definition statements of user-defined commands. These parameters and values are identified by the phrase (<i>For IBM-supplied commands)</i> that immediately follows the parameter keyword (if the entire parameter is for IBM-supplied commands only) or the predefined value to which it applies.

<h3>Keyword (KWD)</h3>
<p>Specifies the keyword name of the parameter being defined. Every CL command parameter has an associated keyword name. Command parameters specified using the parameter keyword can be specified in any order. Parameters may be specified in positional form (without a keyword name) up to the positional limit specified by the MAXPOS parameter on the Create Command (CRTCMD) command.
</p>

<div> <a name="PARM.TYPE"></a>
<h3>Type of value (TYPE)</h3>
<p>Specifies the type of the value that can be specified for the parameter named in KWD. The value can be an integer, a decimal, hexadecimal, or logical value, or a character string (optionally enclosed in apostrophes) that can be a name, date, or time. The value can also be a command. Type one of the following options to specify the parameter type:
</p>
<dl>
<dt><b>*DEC</b></dt>
<dd>The parameter value is a packed decimal number.
</dd>
<dt><b>*LGL</b></dt>
<dd>The parameter value is a logical value of one ('1') or zero ('0').
</dd>
<dt><b>*CHAR</b></dt>
<dd>The parameter value is a character string that can optionally be enclosed in apostrophes. If the character string contains any special characters (not including an asterisk (*)), it <i>must</i> be enclosed in apostrophes. The maximum length of the character string is 5000 characters.
</dd>
<dt><b>*NAME</b></dt>
<dd>The parameter value is a character string that represents a name. The maximum length of the name is 256 characters. The first character must be alphabetic or one of the special characters, $, @, or #. The remaining characters can be alphanumeric, a period, an underscore, or one of special characters, $, @, or #. The name can also be a string of characters starting and ending with double quotation marks (") or enclosed in parentheses. If a special value is used (as in *LIBL or *NONE), it should be specified on the <b>Special values (SPCVAL)</b> parameter.
</dd>
<dt><b>*SNAME</b></dt>
<dd>The parameter value is a character string that represents a name. The maximum length of the name is 256 characters. The first character must be alphabetic or one of the special characters $, @, or #. The remaining characters can be alphanumeric, an underscore, or one of the special characters $, @, or #). The character string can be enclosed in parentheses. If a special value is used (as in *LIBL or *NONE), it must be specified on the <b>Special values (SPCVAL)</b> parameter.
</dd>
<dt><b>*CNAME</b></dt>
<dd>The parameter value is a character string that represents a name. The maximum length of the name is 256 characters. The first character must be alphabetic or one of the special characters, $, @, or #. The remaining characters can be alphanumeric or one of special characters, $, @, or #. The character string can be enclosed in parentheses. If a special value is used (as in *LIBL or *NONE), it must be specified on the <b>Special values (SPCVAL)</b> parameter.
</dd>
<dt><b>*PNAME</b></dt>
<dd>The parameter value is a character string that represents a path name string. Optionally the path name string may be enclosed in apostrophes. If the path name string contains any special characters (not including an asterisk (*)), it must be enclosed in apostrophes. The maximum length of the path name string is 5000 characters.
</dd>
<dt><b>*GENERIC</b></dt>
<dd>The parameter value is a character string that represents a generic name. A generic name contains a maximum of 255 characters followed by an asterisk (*) and must conform to the rules for generic names. The name identifies a group of objects whose names all begin with the characters preceding the asterisk (*). If an asterisk (*) is not included, the system assumes that the generic name is a complete object name.
</dd>
<dt><b>*CMDSTR</b></dt>
<dd>The parameter value is a command that will be checked for validity by the system. It is passed to the command processing program as a command string.
<p>The command analyzer rebuilds the command string when it checks it for validity. When the command is rebuilt, keywords are added to parameters that were specified positionally, parameters can be reordered, and parameters that contain characters that cannot be printed (X'FF' and X'00 - X'3F') are converted to hexadecimal notation. As a result, the rebuilt command string may be substantially longer than the original command string. If the length of the rebuilt command is longer than the allowed length specified with the LEN keyword, the command will fail.
</p>
<p>
<b>Note: </b>Selective prompting is not allowed with the *CMDSTR parameter.
</p>
</dd>
<dt><b>*DATE</b></dt>
<dd>The parameter value is a character string that represents a date. When entering the command, the year may be specified with either 2 digits or 4 digits. If a 2-digit year is specified, the date is assumed to be in the range of January 1, 1940 through December 31, 2039. If a 4-digit year is specified, the date may be in the range of August 24, 1928 through May 9, 2071. When it is passed to the command processing program, it is always passed in the format <i>Cyymmdd</i>, where C = century, yy = year, mm = month, and dd = day. The century digit is set to 0 (zero) for years 19xx, and it is set to 1 (one) for years 20xx. When a date value is specified in this PARM statement, it must be specified in one of the following formats <i>mmddyy</i>, <i>mmddyyyy</i>, or <i>Cyymmdd</i>. When a user types a date in the command at run time, it must be specified in the job-date format. The job date separator may be used when the date is entered. If the separator character is used, the date must be enclosed in apostrophes.
</dd>
<dt><b>*TIME</b></dt>
<dd>The parameter value is a character string that represents a time. It is passed to the command processing program in a 6-byte character string as <i>hhmmss.</i>, where hh = hours, mm = minutes, and ss = seconds. Values specified in this statement must be in the format <i>hhmmss</i> When a user types a time in the command at run time, it must be specified in the format <i>hhmmss</i>. The job time separator may be used when the time is entered. If the separator character is used, the time must be enclosed in apostrophes.
</dd>
<dt><b>*HEX</b></dt>
<dd>The parameter value is hexadecimal in form. The specified characters must be 0 through F. They are converted to hexadecimal (EBCDIC) characters (2 hex digits per byte), right-justified, and padded on the left with zeros. If the value is enclosed in apostrophes, an even number of digits is required. If the value is not enclosed in apostrophes, an even number of digits is <i>not</i> required.
</dd>
<dt><b>*ZEROELEM</b></dt>
<dd>The parameter is always considered as a list of zero elements, for which no value can be specified in the command. It is used to prevent a value from being entered for a parameter that is a list even though the command processing program expects one. For example, if two commands use the same command processing program, one command could pass a list for a parameter and the other command may not have any values to pass. The second command would be coded with *ZEROELEM specified for this parameter.
</dd>
<dt><b>*X</b></dt>
<dd>(For IBM-supplied commands) The parameter value is a character string, variable name, or numeric value. The value is passed as a numeric value if it contains only digits, a + or - sign, or a decimal point; otherwise, it is passed as a character string.
</dd>
<dt><b>*INT2</b></dt>
<dd>The parameter value is an integer that is passed as a 2-byte signed binary number.
</dd>
<dt><b>*INT4</b></dt>
<dd>The parameter value is an integer that is passed as a 4-byte signed binary number.
</dd>
<dt><b>*UINT2</b></dt>
<dd>The parameter value is an integer that is passed as a 2-byte unsigned binary number.
</dd>
<dt><b>*UINT4</b></dt>
<dd>The parameter value is an integer that is passed as a 4-byte unsigned binary number.
</dd>
<dt><b>*VARNAME</b></dt>
<dd>(For IBM-supplied commands) The parameter value is a CL variable name that is passed as a character string.
</dd>
<dt><b>*CMD</b></dt>
<dd>(For IBM-supplied commands) The parameter value is a command. For example, the IF command has a parameter called THEN whose value must be another command. The command is checked for validity by the system.
</dd>
<dt><b>*NULL</b></dt>
<dd>The parameter value is a null pointer, which can be used as a constant place-holder. A DEP statement or the REL and RANGE keywords of other PARM statements may not refer to the value of a parameter defined with *NULL specified for this parameter.
</dd>
<dt><b><i>statement-label</i></b></dt>
<dd>Specify a qualified name or a mixed list of values. The statement label specified here is the statement label that identifies the first of a series of QUAL or ELEM statements that further describe the qualified name or the mixed list being defined by this PARM statement.

<h3>Value length (LEN)</h3>
<p>Specifies the length of the parameter value that is passed to the command processing program. This parameter is not allowed if *INT2, *INT4, *UINT2, *UINT4, *DATE, *TIME, *CMD, *ZEROELEM, *NULL, or a statement label is specified for the <b>Type of value (TYPE)</b> parameter. With other values specified for the <b>Type of value (TYPE)</b> parameter, this parameter has the following applications:
</p>
<ul>
<li>If *DEC is specified for the <b>Type of value (TYPE)</b> parameter, the decimal length is specified in the form (length1 length2), where length1 specifies the total number of digits in the value (including the decimal portion), and length2 specifies the number of allowable decimal digits to the right of the decimal point. The value for length2 is optional. Zero is assumed if it is not entered.
</li>
<li>If *CHAR, *NAME, *SNAME, *CNAME, *CMDSTR, or *VARNAME is specified for the <b>Type of value (TYPE)</b> parameter, only length1 is specified. It identifies the number of characters passed.
</li>
<li>If *HEX is specified for the <b>Type of value (TYPE)</b> parameter, only length1 is specified. This length specifies the number of characters passed after the hexadecimal digits have been converted to character digits. Because 2 hexadecimal digits are converted to 1 decimal digit, the number of hexadecimal digits converted is twice the value of this length.
</li>
<li>If *X is specified for the <b>Type of value (TYPE)</b> parameter, the LEN parameter is used as follows:
<ul>
<li>For character data, length1 specifies the minimum length to be passed. If a longer value is entered, the entire value is passed.
</li>
<li>For decimal data, length2 and length3 specify the length and decimal positions for a constant value. If a variable is entered, it is passed according to the variable attributes.
</li>
<li>For a logical value, length1 specifies the length of the value, which is always 1.
</li>
</ul>

<h3>Return value (RTNVAL)</h3>
<p>Specifies whether a value is returned by the command processing program through the parameter being defined in this PARM statement.
</p>
<dl>
<dt><b><u>*NO</u></b></dt>
<dd>No value can be returned in the parameter being defined. The parameter is an input parameter only.
</dd>
<dt><b>*YES</b></dt>
<dd>A value is to be returned by the command processing program in the parameter. A CL variable name must be specified (on the CALL command) to receive the value. *YES is valid only if *DEC, *CHAR, *LGL, *INT2, *INT4, *UINT2, *UINT4, or *X is specified for the <b>Type of value (TYPE)</b> parameter. Also, *YES is valid only on commands that are limited to CL programs. That is, if either *BPGM or *IPGM is specified in the Create Command (CRTCMD) command that uses the source file containing this PARM statement, *YES can be specified here. *YES must be specified on the <b>Varying length (VARY)</b> parameter, if *YES is specified here and on the <b>Pass attribute byte (PASSATR)</b> parameter. If *NO is specified for the <b>Allow variable names (ALWVAR)</b> parameter, or if the <b>Maximum values allowed (MAX)</b> parameter has a value of greater than 1, *YES is not valid. *YES is also not valid with the following parameters:
<ul>
<li>Constant value (CONSTANT parameter)
</li>
<li>Default value (DFT parameter)
</li>
<li>Restricted values (RSTD parameter)

<h3>Relational expression (REL)</h3>
<p>Specifies the relationship between the parameter value of this parameter and the value of a constant or another parameter. If a keyword is specified, it must be preceded by an ampersand (&amp;) to indicate that it is the value of the keyword that is to be tested. The value associated with the referred to keyword is the value passed to the command processing program, not the user-specified value. If the relationship is with another parameter whose value is a list of values or a qualified name, the first value only is used in the comparison.
</p>
<p>To specify the relationship, enter one of the following relational operators followed by either a constant or the keyword name of the other parameter (which must be preceded by an &amp;).

<h3>Range of values (RANGE)</h3>
<p>Specifies the range, or limits, for the parameter value. The parameter value must be greater than or equal to the lower limit value specified, and it must be less than or equal to the upper limit value specified. For example, 15 would be valid if RANGE was specified as (0 16).
</p>
<p>For nonnumeric data types, such as character, the range of values and the data specified are right-justified and padded on the left with blanks. A numeric range should not be used to define an interval for nonnumeric data unless leading zeros are specified or the data is only 1 character in length.
</p>
<p>Variables can be coded for this element.
</p>
<p>The upper and lower limits of the range can be specified either by a keyword representing the value or by the value itself. If a keyword is specified, it must be preceded by an ampersand (&amp;) to indicate that the value of the keyword is to be tested. The value of its parameter at the time of the check is used to determine the range. The value that is tested is the value passed to the command processing program, not the user-specified value. If the keyword identifies a list of values or a qualified name, only the first value is used as the range limit. A keyword may not refer to a parameter that is defined with *NULL specified on the <b>Value to pass if unspecified (PASSVAL)</b> parameter. This parameter is not valid with *NULL specified on the <b>Value to pass if unspecified (PASSVAL)</b> parameter.

<h3>Special values (SPCVAL)</h3>
<p>Specifies a list of up to 300 entries that define special values that can be entered on the parameter. Each entry specifies a character string (a from-value) that can be entered even though it may not meet all validity checking requirements. If the entered character string matches the from-value of one of the entries, and the to-value is specified, the string is replaced with the to-value and is then passed to the command processing program (CPP) without further checking. If the to-value is omitted, the from-value is passed to the CPP. This parameter is not valid if *YES is specified on the <b>Return value (RTNVAL)</b> parameter, or if *CMD, *CMDSTR, *X, *ZEROELEM, *NULL, or a statement label is specified for the <b>Type of value (TYPE)</b> parameter.
</p>
<p>The from-value is a character string, but the to-value can be anything that is passable. However, for TYPE(*DATE) the to-value must be specified not quoted in the <i>mmddyy</i>, <i>mmddyyyy</i>, or the <i>Cyymmdd</i> format. If a CL variable is used for the from-value, its type must be *CHAR. The to-value must be no longer than specified on the <b>Value length (LEN)</b> parameter, and, if *DEC, *INT2, *INT4, *UINT2 or *UINT4 is specified for the <b>Type of value (TYPE)</b> parameter, the type of the to-value must be the same. If the <b>Type of value (TYPE)</b> parameter is a character type (such as *CHAR, *LGL or *DATE), the to-value must be a character string. Character constants specified in this parameter can be no longer than 32 characters. If a to-value is not specified, the from-value must be passable.
</p>
<p>If a to-value of *CURLIB is specified, the name of the current library, rather than the value *CURLIB, is passed to the CPP. If the from-value is *CURLIB and no to-value is specified, or if the to-value is *CURLIB and it is enclosed in apostrophes, the value *CURLIB is passed to the CPP.

Any one of the single values can be entered instead of a list of values or a qualified name that the parameter is defined to accept. Each entry specifies a character string (a from-value) that can be entered. If an entered character string matches the from-value of one of the entries and the to-value is specified, the data is replaced with the to-value and is then passed to the command processing program without further checking. If the to-value is omitted, the from-value is passed to the command processing program.
</p>
<p>The to-value (or the from-value, if the to-value is omitted) must be passable, as specified in the <b>Special values (SPCVAL)</b> parameter. Character constants specified in this parameter can be no longer than 32 characters. This parameter can be specified only if the <b>Maximum values allowed (MAX)</b> parameter is greater than 1 or if TYPE is specified as a statement label of a QUAL or ELEM statement. Each single value can only be substituted for a list of values or a qualified name; it cannot be a list item or qualifier. It is passed as the first and only element of the list.

<b>Note: </b>Required parameter statements must precede optional statements. If required parameter statements are not specified first, the system assumes that the specified parameter is optional, and the minimum number of values for required parameters is ignored.
