|

|
|
<div><p>There are restrictions on the case used for characters in variables.</p>
|
||
|
|
<p>Reserved values, such as *LIBL, that can be used as variables must always
|
||
|
|
be expressed in uppercase letters, especially if they are presented as character
|
||
|
|
strings enclosed in apostrophes. For instance, if you wanted to substitute
|
||
|
|
a variable for a library name on a command, the correct code is as follows:
|
||
|
|
</p>
|
||
|
|
<pre>DCL VAR(&LIB) TYPE(*CHAR) LEN(10) VALUE('*LIBL')
|
||
|
|
DLTPGM &LIB/MYPROG;</pre>
|
||
|
|
<p>However, it would be <em>incorrect</em> to specify the VALUE parameter this
|
||
|
|
way: </p>
|
||
|
|
<pre>DCL VAR(&LIB) TYPE(*CHAR) LEN(10) VALUE('*libl')</pre>
|
||
|
|
<p>Note that if this VALUE parameter had not been enclosed in apostrophes,
|
||
|
|
it would have been correct, because without the apostrophes it would be translated
|
||
|
|
to uppercase automatically. This error frequently occurs when the parameter
|
||
|
|
is passed as input to a procedure or program from a display as a character
|
||
|
|
string, and the display entry is made in lowercase.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> The above paragraph does not take into account the fact that conversion
|
||
|
|
to uppercase is language dependent. <strong>REMEMBER</strong>: Relying on the system
|
||
|
|
to convert values to uppercase may produce unexpected results.</div>
