Excel and REGISTER() Conventions

ID: Q27776

The information in this article applies to:

Microsoft Excel for Windows, versions 2.x, 3.0, 4.0, 4.0a, 5.0

Question:

Does Excel expect REGISTER()ed routines to obey the Pascal calling convention? If so, is it safe to allow for the reversal of the argument order and CALL() a C-style routine anyway, or will I eventually overflow (or underflow) Excel's stack?

Response:

You must use the Pascal calling convention. It is a Windows requirement, not an Excel requirement.
