programming / variables

[jcvanhaeften@xxxxxxxx]

I didn't bring my xy-manual along, thinking I knew it by hart -

now I know that isn't true at all
I forgot how to pass, when running an xy-program (I still use .PM
as an suffix for programs) info/data from the command-line to a
variable

fot instance in the command-line:
run prog.pm 123
or
run prog.pm,123 (what's the way??)

and I want this 123 in a variable
say  or 

(dubbel-brackets asumed above)

How know or remeber
how to do that
