Hi, Zentara: I fiddled [far more than one would expect], and used the recently posted write to file format above, and it works with the top line, "#! /usr/bin/perl -w". But, if I add "use strict;" at the top of the script, I can't compile: tompoe@aether:~/perlStuff > createpng Global symbol "$im" requires explicit package name at ./createpng line 5. Global symbol "$red" requires explicit package name at ./createpng line 7. Global symbol "$im" requires explicit package name at ./createpng line 7. Global symbol "$blue" requires explicit package name at ./createpng line 8. Global symbol "$im" requires explicit package name at ./createpng line 8. Global symbol "$im" requires explicit package name at ./createpng line 11. Global symbol "$blue" requires explicit package name at ./createpng line 11. Global symbol "$im" requires explicit package name at ./createpng line 13. Global symbol "$red" requires explicit package name at ./createpng line 13. Global symbol "$im" requires explicit package name at ./createpng line 19. Execution of ./createpng aborted due to compilation errors. So, since we're here, do you understand what the message is? A required explicit package name? I'm lost. Thanks, Tom -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
