upgrade 9.1D to OpenEdge 10

[emichael]

Hi,
I have searched high and low and cannot get an answer to a simple question. When we upgrade from Progress 9.1D to OpenEdge 10 (running on HP-UX), would we need to recompile all our programs?

Yes.

See eg:

Without A Doubt

Think about it. The current compiled Progress code (rcode) has a version stamp, so when ProWin32 tries to execute the code, type mismatch will occur.
The rcode will define that the instruction block is for Progress 9.x, then Prowin32 attempts to execute, the instruction hits the compiler which is 10.x so Progress goes ehh, oh no, falls over and complains.
