Can't call method "args" without a package or object reference

himanshu.padmanabhi has asked for the wisdom of the Perl Monks concerning the following question:

This is regarding my thread. Replace number by args<number>. http://www.perlmonks.org/?node_id=751951

$cmd =~ s/([0-9])/args$1/g;
[download]

This solution is working well.But a small chance here,I wanted actually like this,

$in{'cmd'} =~ s/([0-9])/$in{args$1}/g;
[download]

I am getting error here as,

Can't call method "args" without a package or object reference at /usr
+/file1.cgi line 399.
[download]

What should I do?

When Perl sees `args$1` [download] it interprets that as: `args($1)` [download] that is, a function call. You want to have `args$1` as a string and to use it as a hash lookup. This means you have to quote it: `"args$1"` [download]	[reply] [d/l] [select]

it interprets that as: `args($1)` [download] I think it's rather seeing it as `args $1` (indirect method call, like in `args SomePkgOrObj`). With `args($1)`, it should complain `Undefined subroutine &main::args called at...` </nitpick>	[reply] [d/l] [select]

$in{'cmd'} are in this type, `1. -p 1 -t 2 3 2. 1:2 3. --name 1 --limit 2` [download] I want it to change to, `1. -p $in{'args1'} -t $in{'args2'} $in{'args3'} 2. $in{'args1'}:$in{'args2'} 3. --name $in{'args1'} --limit $in{'args2'}` [download]	[reply] [d/l] [select]
