Chris,

I'm not sure why DATTIM=all doesn't do the trick for you.

Although, you may be having a simple problem which you can see
when you run interactively.

Using:
 SFFILE   = $GEMDATA/mos/2000072612_nmos.gem
 GDFILE   = ngmgrid.gem
 SFPARM   = tmpf
 DATTIM   = all
 DTAAREA  = dset
 GEMPAK-OABSFC>

when I run, I get:

OABSFC PARAMETERS: 
<stuff>

Enter <cr> to accept parameters or type EXIT:

Time:                   000726/1800
<morestuff>
Pass1, pass2

Then the prompt again for the next time:
Time:                   000726/2100
Enter <cr> to accept parameters or type EXIT:


So, if your oabsfc invocation had:

oabsfc << EOF
<stuff>
r

e
EOF

Then the program would exit after the first time is gridded if you
have the exit at that point. It would be possible- but combersome to
use the above, with a return for every prompt from the program.

The alternative is to simply use:

oabsfc << EOF
$respond = n
<stuff>
run

EOF
oabsfc << EOF1
$respond = yes
exit
EOF1

The $respond GEMPAK parameter tells the program not to prompt you for response 
each time.
You will definitely want to remember to set this back to $respond=yes if you 
are going 
to do anymore work in this directory...with $respond=no, the program exits as 
soon
as it is done, without gining you a chance to do anything else.

The other solution is to use the sfctime program I mentioned to you last time
to get the times in the file, then foreach time, run oabsfc.

If this isn't the problem you are having, let me know.
