Re: Uncaught Errors in Interactive Programs and the Users that Ignore the Errors

Sample

MONMSG CPF0000 GOTO(ERRSTUFF)
...
Page 20
...
CPYF MYLIB/MASTERFILE QTEMP/WORKFILE...
DLTF MYLIB/MASTERFILE
CALL ProgramToRecreateMasterFile
...
Page 27
...
goto end
errstuff:
/* handle errors with pretty email */
end:

Now, instead of taking an R when ProgramToRecreateMasterFile blew up I
have no MASTERFILE. And my QTEMP copy of WORKFILE is gone. But at least
I have pretty email.

The other problem is that developers often get lazy by relying upon the
generic top level MONMSG and errors go on for years unnoticed - seen
that. But that's mostly without the goto.
