in reply to Re^2: Splitting a large file into smaller files according to indexes
in thread Splitting a large file into smaller files according to indexes

it is initialised to -1 (or whaterver other value your mrule number will not take) in order to force the opening of the file upon seeing the mrule pattern for the first time.

Glad it worked (it's Perl after all) but I stress that it is untested by me for more complex cases.
