Home: Perl Programming Help: Beginner: I'm having trouble with -w

DrZed User Jun 7, 2000, 7:14 PM Post #1 of 3 (451 views) I'm having trouble with -w Can't Post When I don't include the flag, my cgi runs fine. #!usr/bin/perl However, when I use a -w, the program totally hangs. It doesn't generate any error messages, it just performs some endless loop. #!usr/bin/perl -w Is there a way of telling what might cause this? I thought that the program would still run the same way under a -w flag, and the only difference would be what's writting into the error log. However, this isn't the case with my program. Dr. Zed

Actually, running it from the command line without the -w was just as expected (a bunch of html being dumped to the screen). Running it with the -w from the command line, and sending the output to a file.... e.g.: C:\> perl script.cgi > output.txt .... caused around 100 lines of: Use of uninitialized value at .... It's a shame that I can't send this data to an output file, because it scrolls by way too fast. I'll have to attack it from the end and work my way up. I even tried to pipe the output to more, but only the standard output is affected. The warnings are handled seperatly. Thanks for the tip. At least now I know that I should clean up my code. Dr. Zed
