Tom -

IMO, This was not code generated by the JDE CASE tool.  I have been working
with JDE software since 1987, and I have never seen anything like this in
any JDE program.  Some human bozo coded it.  I have seen many modified JDE
programs that had stupid modifications like this.

Once, when I was working at a client in the Dallas area, a JDE _employee_
came in to fix a problem with the invoice print program.  Later, when the
program was still working incorrectly, I looked at the mods he made. Instead
of fixing the real problem, he had coded a GOTO around a block of code so
that the program would not bomb.

This speaks to the need of having a systematic way of QA'ing programs.  In
college I was taught the structured methodology and using peer reviews, the
"ego-less" approach to reviewing code.  Too often the mavericks slip things
in the code that should be caught _before_ the program gets into production.
