#N:ubc-medgen:3400009:000:2237 ubc-medgen!naomi Mar 3 11:26:00 1983 Today, trying to be a good citizen, I ran the following: nice -19 S < cmd > output & (OK, I should have run the following: nice -19 S BATCH cmd output & but as it happens, exactly the same problem arises if you do it that way.) In the first line of cmd, I try to save all the relevant data sets, in case I mess them up in the subsequent commands. Unfortunately, I made a mistake in the save command, but Bug 1: S, instead of quitting, continued to process the command file. You are supposed to be able to set the sourceexit command using options, but this doesn't work on our system. However, I didn't realize that S was still running, so I corrected the error and reran the program. Unfortunately, following the suggestion in section 9.1 of the manual, my datasets are prefixed by directory names so Bug 2: I could not save my data sets because I did not have the appropriate subdirectory under sdata. (I guess this isn't really a bug, but that suggestion in the manual should go, since datasets prefixed by directory names do not work "properly" with several commands, including list. For me, however, the benefits of using subdirectories still outweigh the disadvantages.) Nevertheless, after printing the error message, S continued to run, so I then had two versions of S, both changing unbacked up my datasets, in the background. Checking on another background job, I discovered that S was still running, so I brought one into the foreground, and out. Then I brought the other one into the foreground, hit , and found myself in Bug 3: an infinite loop of: Dumped jstkrl: tried to release < 0 items Several screens of this message convinced me that I could not break my way out, so I logged onto another terminal and Bug 4: I typed S KILLEM, which killed, not only my S job and all its subprocesses but also my stopped emacs job and all its subprocesses. Of course, it did not set emacs exit switch, so emacs protested (fortunately not too violently, when I tried to start it up again.) Ah well, in future I will back up files interactively.
