If the records are as fixed as they appear, substr or unpack would be better than matching a regular expression:

# assume the current line is in $_ my $foo = substr $_, 5, 40; # or else my ($foo) = unpack "x5 A46", $_;
The unpack solution will trim trailing space, because of the "A" template, and is better if the text to capture has varying width. If 'SUBCASE' is not at fixed offset, index can find it to be used in the unpack template.
