Subject: End and the syntax parser

This is something for everyone to toy with over the holidays (sorry for the
pun).

Now I think this same point has been discussed previously but without any
action being taken.  Should anything be done is the point of the email.

One of the filePro programmers working here had a problem the other day that
some code didn't seem to be running.

The processing table passed syntax check, created the tok file, etc and ran
to a particular point and then stopped with the rest of the code not
running.

Now this is Sco 5v6.0.0 with filePro 5.0.14R4.

After spending serious time trying to work out why the code wasn't running,
no goto's over the code, no gosub's without returns, etc I had a look for
them and found the problem.

There was a long variable called "EndDate" being used.

The fat fingered, well in this case light fingered, programmer instead of
entering:

EndDate=lookup(6)

had entered:

End=lookup(6)

Now I know Ken has mentioned before that everything after an "end"
statement is ignored when being parsed as it will never be processed.

I am of the mind though that this is a syntax error as a "reserved"
word is being used as a variable and I feel there should have been an error
thrown at syntax check time.

I believe the following rules should be checked.

1. If there is anything after "end" on a line that is not a comment then it
is an error.
2. Reserved words should not be allowed as variables and if attempted to do
so as in this example then it is an error.

What do the rest of you think?
I am wrong in thinking this should throw and error?

Cheers, Merry Christmas and a safe and prosperous New Year.

Ken
