The $Cms function determines if the Model 204 Online is running under CMS.
Syntax
%cms = $Cms
$Cms accepts no arguments; it returns a 1 if the Online is running under CMS, or it returns a 0 otherwise. n
Usage notes
$Cms can be used before running any operating system specific code. For example, the following code fragment sets global variable NEXTPROC to PROC.CMS if running under CMS, or it sets NEXTPROC to PROC.MVS, otherwise:
if $cms then %rc = $setg('NEXTPROC', 'PROC.CMS') else %rc = $setg('NEXTPROC', 'PROC.MVS') end if
