/*Scans the sym table and checks
each $LK,"HTT_DEFINE_STR",A="MN:HTT_DEFINE_STR"$ entry to see if
it only occurs once in files.

It's a brute force solution, but
gets the job done... slowly.

$LK,"Find",A="MN:Find"$() returns a count of matches.

$LK,"FileOcc",A="MN:FileOcc"$() is $LK,"Find",A="MN:Find"$() with
output $LK,"Silent",A="MN:Silent"$().
