and so on
What do the <> with the 'lines' to the right mean?
(I do seem to have a problem on line 89 which is a regex with the /x
modifier)
Hello Anne
The error means that you have used $9 in a string, either
"the ninth capture is $9"
or the equivalent
"the ninth capture is " . $9
but $9 has no value. It would be set by a successful regex that has nine
or more captures, so either a regex hasn't matched or the capture is in
a branch of the regex that hasb't matched. Or you've counted your
captures wrongly etc.
The
... at pg_delim2htm_01.pl line 89, <> line 4.
means perl was executing line 89 of the pg_delim2htm_01.pl program,
having read 4 lines from the input file using <>
HTH,
Rob
