This code works on XP but not Windows 7 (Vista not tested)

Help files for exitfunction and endfunction say:

Quote: "Syntax

EXITFUNCTION Variable"


and

Quote: "Syntax

ENDFUNCTION Variable"


Your code isn't using variables.

The code should therefore be rejected by the compiler.

Agreed - forgot to suggest that.

Also, the Help file for exitfunction mysteriously implies that things other than variables can be returned.

I posted a similar bug report and I'm guessing it could be the same problem.

A literal can replace any instance of a variable where the operation only reads from it (and doesn't require an address). So it should work fine in this case.

The evidence suggests your theory is wrong.

If you follow the syntax given in the Help file (in this case ) then things work as expected. What more can you ask?

I'm not sure why you think there would be some exception for this operation that would only allow variables (and not literals) to be used.

It's standard in most (if not all) programming languages that any direct value (ie. not passed by address) argument can be either a variable or a literal, they both function the same. I highly doubt DBPro would be any different.

Apart from that, this bug only exists on Vista/7. If it wasn't meant to work correctly in the first place it would not likely work on other operating systems.

I read the Help file. Simples.
