Re: [FWP] Greenhorn coding question

Please note this isn't the correct forum for this type of question.

You didn't read carefully enough.

	If those were both GLOBAL variables, then this would
			   ^^^^^^
	suffice:

	    $text =~ s/\$(\w+)/${$1}/g;  # no /e needed

	But since they are probably LEXICALS, or at least, they could
				    ^^^^^^^^
	be, you'd have to do this:

	    $text =~ s/(\$\w+)/$1/eeg;
	    die if $@;			# needed /ee, not /e

Remove the my's and try again.
