If you could do with a new filename, you could read/write one by one and
then change only the desired entry. Otherwise, that is pretty much the only
method. I'd have to add though, if this file is part of a larger system, and
that single entry needs to be modified more often than the rest, then you
might be better off splitting the file into two files, so you have less
workload to change that entry. That's why some of my Systems keep track of
several files (especially my LSSM, having something around 7 files I
think...).

Nope, that's the shortest possible way to increment a variable, unless you
delete the spaces... ;-)
