Because quotes are quotes, `print "module( ... ... $display("The time is %d",$time)\n"; ^_OPEN ^_CLOSE ^_OPEN ^_CLOSE` [download] Shortest way to fix it is with alternate delimiter ({} needs to be balanced) `print qq{module( ... ... $display("The time is %d",$time)\n};` [download] interpolation, read about it in perlintro, perlop, and Modern Perl, search for "interpolat", in short, single quotes do not interpolate, http://perldoc.perl.org/perltrap.html#Interpolation-Traps and http://perldoc.perl.org/perlop.html#Quote-and-Quote-like-Operators	[reply] [d/l] [select]

Rather than your vague problem description, in future please provide a precise, specific code snippet (embedded in `<CODE>...</CODE>` tags) of what is not working for you. An example of such a specific code snippet is: `use strict; use warnings; print "module( ... ... \$display(\"The time is %d\",\$time)\n";` [download] which works for me, printing: `module( ... ... $display("The time is %d",$time)` [download] You might consider using single quotes or here documents for this type of thing (see the links provided by anonymonk above for details).
