When calling procedures in Microsoft Macro Assembler, you must watch
the stack manipulations within the called procedure.

If several items are PUSHed onto the stack, they must be POPped off in
the same number. This is necessary because when the RET is encountered
at the end of the procedure, it expects the return address to be on
the top of the stack.

This problem can be avoided by temporarily storing the return address
in a location other than the stack and then PUSHing it back on before
the RET. However, because the results may not be consistent, this
workaround is not recommended.
