Several adequate mechanisms were provided at the time (plus your
unworkable one).

The only suggestion was ugly: overwriting a file.

There was one process that we couldn't do from within
the program, so the program writes a sequence of commands
to a file, "add"s it to the run (which means it starts
executing when this program stops), and finishes.
The last statement in the file re-executes the checker to
check that final process.

a CALL "SYSTEM" to the calling COBOL app.

So that was three, which counts as 'several'.

The point about overwriting the file before the CALL "SYSTEM" is that
if the CALL fails, or the SYSTEM fails, or the command file fails,
then the program will not pick up the previous 'result file' which may
still contain 'success'.

These failure safeguards should be readily understood by someone who
is no longer a newbie.

I'd rather have 'looks ugly' than your 'does ugly' anyday.
