Hi - Yea, I just tried a c preprocessor, but, guess what? All perl comments (they start with # remember) gave 'invalif preprocessor directives...

If you want the C preprocessor, check out the -P option to Perl. But I'd suggest that is not a good solution to most problems. > Hi, > > in C: > #ifndef __DEBUG__ > #define MYD(x) x > #else > #define MYD(x) > #endif > > and in perl ? > > (the question being: how can I do macros within perl, and how can I pass > "things" to the perl interpreter? ) > > or is there any other approach to this ? The approach is usually something like if ($Debug) { } or print "Everything's fine up to here: ", Dumper $data if $Debug; If you're concerned about performance and want to leave your debugging code in place: sub Debug () { 1 } if (Debug) { } This will allow your debugging code to be optimised away if you set the debugging value to something false. You can then get more complicated if you need too. -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
