Thanks Jeff,
I will have to read up on Splice,
The way I am using this to generate html where each line is in a different color,
@colors = qw[ #F0F8FF #00FFFF #7FFFD4 #F0FFFF #F5F5DC #FFE4C4 #4169E1 #8B4513 #FA8072
#F4A460 #2E8B57 #A0522D ];
$color_choice1 = rand ($#colors + 1); #thanks for pointing this out!
This code is in a cgi that when called appends some text to a file and then exits.
So now that I think about it, I will need the last $color_choice to be stored between
cgi calls!
