Does that mean a > function can be declared anywhere in the program (i.e. inside another > function, loop or if block)? the handy dandy autonomous 'function' comes to mind.... the problem of course is that you want to avoid getting way esoteric - since that will need more documentation - and can make the code maintenance harder. A reasonable rule of thumb that I offer is the old school pascal trick - #!/usr/bin/perl -w use strict; <otherUseFooHere> use vars qw/<varlistHere>/; #so we remember what was global use subs qw/<listOfSubs>/; #--------------- # list out our globals here - initialize them here. #------------- # our functions #----------------- # the main loop this way your sub's are declared before they are used in the main loop and hopefully they do not need get interwoven too badly. This way when You notice that only the main changes - it's clearly obvious that you should just Whip Out the h2xs - make a module of it all - and shorten up your 'scripts'.... ciao drieux --- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
