Thread: SAC in a shell script with PAUSE

Milton and Januka,

The complexity here is that sac is wrapped in a shell script. In this case a HERE Document or sac receives it input directly through standard input via the shell. Sac is behaving as expected.

Sac reads the "pause period off" command and then pauses for the next string of text. In the set of commands presented, QUIT is the next text string and this is consumed by the PAUSE command. After that the script ends with "END', and this is where sac complains about "SAC being executed in a script " or "SAC Error EOF/Quit"

Adding a second QUIT will avoid the "SAC Error EOF/Quit" message.

Changing the initial QUIT to anything will produce the same results.

I would either suggest to use "pause period 3" (as previously suggested) or use PPK. PPK will not move on until you have exited from picking mode (with a Q).

I hope this helps.

Brian

You are right, with PAUSE PERIOD OFF give an error and no wait for carriage return.

No Milton, it does not pause and sac throws out the error message I copied in my earlier message. Yes, if I have something like PAUSE PERIOD 3, it works fine. This is why I suspect that it is might be a bug.

Thanks !

Januka.

Hi,

PAUSE PERIOD OFF

the help said:

:PERIOD OFF: Turn period option off. When this option is off, SAC
pauses until you type a carriage-return.

i not try the script but seems SAC wait you press carriage return in this case.

Cheers,

M.

Hi,
I have the following macro embedded in a shell script, and when I run the shell script, SAC does not "see" the PAUSE command and the lines below it, i.e macro is not paused and QUIT is not executed. I have a feeling that this is a bug. Am I correct? I am using SAC 101.6

sac<<END
R $sacfile
R MORE $synfile
COLOR ON INC L BLUE RED
P2
PAUSE PERIOD OFF
QUIT
END

ERROR MESSAGE:
SAC Error: EOF/Quit
SAC executed from a script: quit command missing
Please add a quit to the script to avoid this message
If you think you got this message in error,
please report it to: sac-help<at>iris.washington.edu

Thanks !
