<< introduces a here document. The syntax and name come from the shell; < filename means get the input from a filename, and << means get the input from right here.

You can find more in the perldata(1) manpage, or the manual for your shell.

Thanks for the info. In any case, I got the $command << EOF from some other perl code provided by the DB maker, and I never felt quite comfortable with it. I guess it works, but I think I'll redo it using system(). Once again, thanks for the help! -chris	[reply]

Re-implementing with `open(CMD,"\| $command");` might be closer to what you want.	[reply] [d/l]
