2 follow-up question if you're up for it:
1.) i turned on strict and was amazed at
all the crap i was doing wrong!
I also tried to incude the library 'warnings'
which failed (my perl is 5.005), is the
shebang -w switch a suitable substitute
for use warnings lib?
Will
#!/usr/bin/perl -w
work in place of
use warnings;

2.) Do you see anything fundamentally flawed with my
use of 'my' instead of local? The strict and -w switch
stopped outputing bad news to my error logs, so am i
okay now? Or is there something else i don't know about
to keep me on the right path to using perl correctly.
#!/usr/bin/perl -w
# this script outputs a gif 
# set color, width, and height
use strict;

&printGIF("FF0000","33","10");

When i say correct use of perl i mean a clean running
program which could open and close millions of times
with no overflow problems.
