Yes, you appear to be right Sandy! I comment out two chunks that are doing stuff with $good_guesses, and it works (well, not the way I want, but I don't get the error). Now I have to figure out how to fix that, because it is now doing it on every run, not just the second pass. I don't know why though, because I'm defining $good_guesses = "" at the top.
A lot of folks have wagged fingers at me for using global variables, and I know what they mean. I just don't know how else to do it! If I want to have a variable that needs to be accessed/updated by the main loop and by multiple subs...how can you do that without storing the variable outside of all the subs? If I try to put it in the loop it will be zeroed out on every loop, and the same with the subs. Any ideas would be appreciated.
This is what I mean:
my $var = 0;
while (condition) {
# read var; gets changed by sub2 on occasion
sub1()
sub2()
}
sub1 {
# read $var; gets changed by sub2 on occasion
}
sub2 {
# update $var
}
