I should add that you, in contrast, are passing the result of the function call

        compareLOGName (@files)

to the sort operator. compareLOGName() does not use its argument list but
rather the global variables $a and $b and returns one integer value indicating
which of them is larger (and probably some warnings about $a and $b being
undefined) - my guess is -1. This value will then be sorted and returned to
whomever is requesting a sorted list of log file names. This is what you are
effectively doing:

        sub sortedPCLogFiles {
          return -1;
        }

I'm sure the result will be surprising ;-).

Regards,
Holger
