Once you have created a SNAP.DAT file in your SNAP subdirectory you can execute SNAP with either of the procedures DOSNAP or SNAP. You will generally want to use DOSNAP and specify that SNAP\ run in a batch queue. Both procedures generate and archive plots using SNAPSUM which is described in Section 5.3. Do not execute these procedures on more than one node at a time.
$ DOSNAP <your initials> <printer> <batch_queue_or_X>With DOSNAP you can execute the SNAP code either interactively or as a batch job by setting the value of the third parameter to either
Xor a particular batch queue. If you don't specify the parameters on the command line, DOSNAP will prompt you for them.
DOSNAP invokes SNAPSUM (Section 5.2) to generate 2-4 pages of graphs. If you select the HL1 printer (located in B235) it will print all the graphs on a single sheet of paper (4-up).
DOSNAP uses the directory TFTR_SNAP: to write the batch job log file and a copy of the SNAP.DAT file where they are kept for one week. To see if you have quota on that disk, do $ SHOW QUOTA/DISK=UTIL/USER=yourname. Please contact Lena Scimeca (firstname.lastname@example.org) if you need quota.
