I'm sure that I've missed something basic, please tell me so. I
want to patch a byte in an ISAM file header (change a key name).
When I use PATCH/ABS the UPDATE command writes a new version of
the file as a sequential file. How can I patch files without a
new version being created?? Do I have to write a program to do
this??

You did miss something basic.
PATCH
/NEW_VERSION
/NEW_VERSION (default)
/NONEW_VERSION
Controls whether a new version of the patched file is created or the
contents of the existing file are modified in place. The
/NEW_VERSION qualifier is used in conjunction with the /ABSOLUTE
qualifier to control whether a new version of the patched file is
created or the contents of the existing file are modified in place.
/NEW_VERSION is the default. If /NONEW_VERSION is selected, the
PATCH command UPDATE will act as a checkpoint operation, that is,
all modifications made to the file are written back to the file
instead of waiting until image exit. If /ABSOLUTE is not specified
with /NONEW_VERSION, /NONEW_VERSION is ignored, that is, a new
version of the file will be created. /NONEW_VERSION will need to be
used when patching large data files when there is not enough disk
space to create a new version of the patched file.
NOTE
If /NEW_VERSION is specified, the file will be
overwritten. No attempt on the part of the user,
including pressing <CTRL/Y>, will prevent this
result. Therefore, you should have a back up copy
of the file before making any attempt to patch it.
PATCH will always issue an informational message at image exit,
indicating that the file is being overwritten.

It is amazing how dumb I can be sometimes. I had a hallway discussion
with a coworker yesterday. I asked my .0 question. I was greeted
with a dumb look and the answer in .1.
