============================================================================

P.S. From another author than the one who wrote the above.
The routine above is excellent, however I had a different version
of PFS FILE and PFS REPORT. If you dont find the locations listed
above try these:

PFS FILE TYPE -> U 9223 YOU SHOULD SEE PUSH BP
MOV AX,DS
MOV ES,AX
(ETC)
IF SO TYPE -> E 9228 EB 2B
TYPE -> W
TYPE -> Q
AND FOLLOW THE DIRECTIONS GIVEN ABOVE ABOUT RENAME ETC.

PFS REPORT TYPE -> U 988F YOU SHOULD SEE PUSH BP
MOV AX,DS
MOV ES,AX
(ETC)
IF SO TYPE -> E 9894 EB 2B
TYPE -> W
TYPE -> Q
AND FOLLOW THE DIRECTIONS GIVEN ABOVE ABOUT RENAME & ETC.

My thanks to the original author who worked so hard to help us.
Please use these routines for your own use. I needed to add DOS 2.1
and place these programs on double sided disks. Don't rip off these
software manufacturers.
