Hi Bill,

Long time no hear...

CONTINUE=NO will only have an effect when the programs being run exit
with a non-zero status.

A quick check of ~mcidas/mcidas2006/src/frmolay.pgm shows that it should set
an error condition upon exiting through a call to 'subroutine finish' which,
in turn, makes a call to 'mccodeset'. What I don't see, however, is a call
to 'mccodeset' with a zero value when there is no error.  I don't know if
this lack is important, but it might be.

I don't think you are doing anything wrong.  Instead, there might be a
problem with frmolay.k.

Please do the following:

1) send me a full listing of the BATCH file whose execution is failing

2) try adding the following line to ~mcidas/mcidas2006/src/frmolay.pgm:

at the beginning of execution in frmolay.pgm, change:

C  RCS stuff
      call ddest(RCSID, 0)

to:

C  RCS stuff
      call ddest(RCSID, 0)
      call mccodeset( 0 )

This will insure that the return code will be zero if no errors occur.

After making the change, you will need to build a new frmolay.k executable:

cd ~mcidas/mcidas2006/src
-- edit frmolay.pgm as per above
make frmolay.k
rm ~/bin/frmolay.k
ln frmolay.k ~/bin

I don't think that this should have any effect, but it can't hurt.  Sending
me the full listing of your BATCH file might start me on the correct path
for figuring out what is happening.

Cheers,

Tom
