Create a .pm file eg xyz.pm and you can have subroutines or
what ever you want can be placed there.
#content of xyz.pm
package xyz;
sub Printit{
print "In module xyz...";
}
1;
#end of xyz.pm
for using this perl module in ur perl program eg abc.pl
# content of abc.pl
use xyz;
xyz->Printit();
#end pf abc.pl
