|
|
<div><p>This describes additional rules involving special characters for
|
|
object naming.</p>
|
|
<p>Additional rules involving special characters (as an extra character) that
|
|
apply to the following types of names are:</p>
|
|
<ul><li>A Command label must be immediately followed by a colon (:). Blanks can
|
|
follow the colon, but none can precede it. A command label name cannot be
|
|
a quoted name.</li>
|
|
<li>A CL variable name must be preceded by an ampersand (&) to indicate
|
|
that it is a CL variable used in a CL program.</li>
|
|
<li>The Built-in functions for CL must be preceded by a percent sign (%) to
|
|
indicate that it is an IBM-supplied built-in function that can be used in
|
|
an expression. A built-in function name cannot be a quoted name.</li>
|
|
</ul>
|
|
<p>These special characters are not part of the name; each is an additional
|
|
character attached to a name (making a maximum of 11 characters) indicating
|
|
to the system what the name identifies.</p>
|
|
<p>The names of i5/OS™ objects,
|
|
CL program variables, system values, and built-in functions can be specified
|
|
in the parameters of individual commands. Instead of specifying a constant
|
|
value, a CL variable name can be used on most parameters in CL programs to
|
|
specify a value that may change during the running of programs. It is the
|
|
contents of the variable that identify the objects and variables that are
|
|
used when the command is run.</p>
