I am checking my 1292-line script for syntax errors. I ran the following

When I expand this out to one item per line,
JOB_WRITEURGFILES =
multiprocessing.Process
(
write2file

,
ENGINEPID
)
;
write2file
(

write2file
(
INPUTMEM

;
JOB_WRITEURGFILES.start()
and I wonder (not being familiar with multiprocessing) if perhaps there
should have been a third ";" after the third write2file in the job
definition.
The mistake is not that it's missing the 3rd, but that the first two
semicolons should have been commas. These are parameters to a function
call multiprocessing.Process()
Everyone: this program seems to be a direct and misguided
transliteration from a bash script. There are dozens of mis-uses like
this of multiprocessing.Process(), due to a severe misunderstanding of
what it does and how it works.
We've tried offering help, and all that's happened is we've been told
that this strange coding style is easier to read.
