[daip] POSSM errors {External}

[Eric Greisen]

This "error" was corrected late in 2023.  If you run the MNJ ($HOME/do_daily.<hostname>) POSSM will be fixed.
The CHANGE.DOC entry for this is:
15999.  November 14, 2023              GINIT                   Eric
        Parseltongue made the horrible decision to bypass AIPS.EXE and
        start AIPS tasks directly.  This leads to the tasks not having
        correct information potentially.  The variable VERNAM which is
        normally TST:, NEW:, OLD:, or CVX: is used by GINIT to read the
        task help file.  Added code to set VERNAM to TST: if it is not
        correctly set.
        Moved nowhere (this is a 31DEC23 only feature).

Subject: [daip] POSSM errors {External}

Dear AIPS team,
I am using ParselTongue software to run AIPS tasks from a Python script
developed by people from the JIVE team. The pipeline is originally designed
to calibrate EVN datasets. The main script is EVN.py which needs external
evn_aips_tasks.py and evn_funcs.py. These are found at
https://www.jive.eu/jivewiki/doku.php?id=parseltongue:grimoire#the_evn_pipeline
I am running their script for non-EVN data. The pipeline can load the data
and then when it goes to the step for plotting, the pipeline crashes where
POSSM is run. The AIPS error message I get is the following

POSSM4: Task POSSM  (release of 31DEC23) begins
POSSM4: UVGET: doing no flagging this time
POSSM4: POSSUV: at visibility number  1
POSSM4: Averaged  6 visibilities from total data set of  196
POSSM4: POSSUV: for antenna(s) GS
POSSM4: Covering timerange  00/18:00:01 -  00/18:00:06
POSSM4: Will plot  128 channels *  8 IFs polarization RR
POSSM4: FILLPL: Amplitude mean:  1.2312E+00  rms:  3.6756E-01
POSSM4: FILLPL: Phase mean:  0.0000E+00  rms:  0.0000E+00
POSSM4: ZDIR: COULD NOT TRANSLATE LOGICAL =
POSSM4: ZDIR:
POSSM4: GINIT ERROR  2 ON OPENING TASK HELP FILE
POSSM4: CATIO: CATBLK  1 IN USE, CAN'T WRITE
POSSM4: DELEXT: CATIO WRITE ERROR  4
POSSM4: REFRSH: ERROR  42 RECEIVED FROM PLCREA
POSSM4: ZFIO: LUN = 26 NOT OPEN IN FTAB
POSSM4: MTICS: GRAPH LABEL WRITING ERROR  1 FROM GVEC
POSSM4: ZFIO: LUN = 26 NOT OPEN IN FTAB
POSSM4: ZCLOSE: DOES NOT PERFORM TEXT FILE CLOSES AS OF 15OCT87
POSSM4: DELEXT: NO EXTENSION FILE OF TYPE PL
POSSM4: Purports to die of UNNATURAL causes

It gets stuck after FILLPL and I do not quite understand what is happening
here. I have never encountered such errors when running the same parameters
inside AIPS.
Do you have any comments or advice on this? At least I would like to
understand why POSSM is crashing like that.
My best regards,
Wara Chamani
