Hi Listers, anyone help with this.

For our sins we are blessed with CA-Filemaster and one of our offshore guys
recently found a new way to screw up based on a command called LASTREC.
this is what happened:

He wanted to edit a trailr record and went into Filemaster to do so. For
reasons as yet unknow decided that the way to do this was to enter
"LASTREC" on the command line, this had the effect of indeed displaying the
last record. He duly edited said record and saved fine. Unfortunately he
did not spot that the record is now shifted 4 bytes to the left.

This I speculated was because the file is VB and for some reason the first
4 bytes of the trailer where taken as the RDW:

here is the actual record:

----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+----9----+----0-
999Z999999997057050222628

here is the record display by Filemaster after the "LASTREC" command:
----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8----+----9----+----0-
99999999705705022262800000099900000000 10802250560029990000000099900000000
10802250560009990000000099

as you can see the record is shifted 4 bytes to the left and filemaster is
displaying what it believes is part of the record(from col 22 on)  as the
length it now thinks it is is the max for the file ie 2k+ (by virtue of
9999 in what it thinks is the RDW). Needless to say, doing the change and
saving the record caused problems.

We now understand what is going on so fine, what we have no idea about is
what is the "LASTREC" command actually doing? There is no mention of it in
any of the manuals etc.

can anyone shed any light on this?

Thanks
Gerry
