SNMX scripting language is used in ASG. Its calling Perl script msgbox.pl & then trying to manipulate the variable paased by perl as shown. 
perl C:\msgbox.pl
set $tmp = $arg.1
echo $tmp

When snmx calls a perl script, the control goes to the perl script, executes it & then comes back to the SNMX. This is similar to calling a subroutine, assuming perl script as a subroutine. Now the problem is that the perl script is not able to pass parameter to the SNMX script which has called it.
