Let me backtrack and provide some background information.
This script processes two files, recapfile, a plain text file, and copy,
and HTML-formatted file.
It reads copy into an array, and recapfile into another array. Then it
writes a new array which contains all the initial lines of the recapfile
array from the first line down to but not including the first line
containing / RESULTS OF BOARD 1/
And here is where it goes wrong ('No <pre> found')
($index) = grep $hfile[$_] eq '<pre>', 0 .. $#hfile;
die 'No <pre> found' unless $index;
I printed hfile using
foreach (@hfile) { print "$_\n"; }
and it looks fine! That is, there is a line with only <pre> on it!!!
