Hi All,
I am writing a program to display POD, functions, Perl FAQ, and programs
and
want to impement two rules for the input:
1. it is Perl module names if the input starts with words or '-m';
2. it is Perl function, FAQ, or program name if it starts with -f, -q, or
-p
respectively.
Here is the test program that I used to test the codes to parse out the
input. I have problem to implement Rule two if there is '-' in the server
name or file names.
Could you help me - you RE and Perl experts!
