I tried that as well and it didn't work, so I thought
the problem was that the directory had to exist before the PreCmd ran,
but I didn't examine the hold message closely enough:

  98.0   pelletm        
2/17 14:25 Error from slot2@condor1: Failed to execute '/var/lib/condor/execute/dir_600967/condor_exec.exe'
with arguments 600: Cannot access initial working directory "case=
1" (errno=2: 'No such file or directory')

Note the space. I had the INT directive specified
with a space after the comma, like so:

CASENUM = $(Process) + 1
CASEDIR = case=$INT(CASENUM, %d)
remote_initialdir = $(CASEDIR)

Spaces after commas and around plus signs make me
happier, I'm funny that way. But that gave a string of "case= 1"
instead of "case=1" as the hold message was trying to explain.
Once I changed it to $INT(CASENUM,%d) it works, and the ssh to the job
places me in the working directory of the executable, $TMPDIR/case=1.

Thanks! It wouldn't be a bad idea to have a note of
these little caveats in the manual - for instance $$([$(Process)+1]) can't
have spaces either.
