in thread calling perl subroutines in other files

tachyon, this is great thank you! But I am still trying to understand this. Where do I want to set this up at, in my MAIN program where the file is created or in the subroutine file where the actual work is to be done? Here are some specific questions: how does the calling program ( call the remote files subrouting) know based off your use vars? Is there a mored detailed man page I can read and maybe I will answer my own questions! thanks derek

The typical construction of a perl widget is to put most/all your subroutines in one or more modules. These modules are your 'subroutine files'. You can save them anywhere. In your script you "use lib '/my/modules/are/here'" to tell Perl where to look for your modueles and then use whichever of your modules you want. Typically the subroutines in one module all relate to one sort of thing. For example DBI is a module for database accesss, Digest::MD5 gives you MD5 hashing.....

There is plenty of info in the perl docs. See perlman:perlmod perlman:perlmodlib perlman:perlmodinstall perlman:perlnewmod

cheers
