I have gotten a new random number library together which reimp,ementes the srand and rand functions according to Knuth (Thanks, Bill!). Anyway, I wanted to create a directory for the libraries I'm collecting, so I created a library called ~/.perlLib where I symbolically link to all of the perl libraries I've FTP'd or created. The problem is, when I say; require "~/.perlLib/random.pl"; I get the error: Can't locate ~/.perlLib/random.pl in @INC at roll line 3. So, I tried this at the top of my program: #!/usr/bin/perl -I~/.perlLib to add ~/.perlLib to the @INC array, and it's there when I look, but the same error occurs. What am I doing wrong? jas -- -------------------------------------------------------------------------- Jeffrey A.

The problem is that ~/... is not a proper filename (unless in your current
directory you have a directory named '~'.
The expansion of ~ to your home directory is a function of the shell (and
not all shells do this).
So try to let the shell do the expansion:
require <~/.perlLib/random.pl>;

That's cute, but a lot less efficient (currently) than saying
require "$ENV{'HOME'}/.perlLib/random.pl";
or, more to the point,
unshift(@INC, "$ENV{'HOME'}/.perlLib");
require "random.pl";
