You can get that sort of thing if you apply a substitution to one of the capture variables: `$1 =~ s/1/2/;` [download] DWIM is Perl's answer to Gödel	[reply] [d/l]

as shmem said, you have to post code. additionally, you forgot to post the complete error message. normally such an error message shows the file and line where it occurred. you wouldn't go to the doctor and say "it hurts" without telling the doctor where it hurts, right?	[reply]

Without some code there's no way we can tell what's going wrong better than you. See I know what I mean. Why don't you? --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.

Perhaps you could use caller within a $SIG{__DIE__}/$SIG{__WARN__} handler to trap the error and dump some additional information. Hopefully the call stack will give you enough information to find the error. Otherwise you may need to dump the arguments to each of the routines in the call stack.	[reply]

In my experience that error occurs when I miss off the dollar sign on a variable. `$my_variable = 1; # what I meant to type my_variable = 1; # what I actually typed` [download] So that would explain it. Why the error would happen once in twenty times is still a puzzle though. As everyone else has said, show us your code.
