; Return value
~~~~~~~~~~~~~~
1. invoke APICALL Parameters etc ....
mov YourVal, eax

2. Use the conversion procedures in thr MASM32 library to convert a DWORD to a string for display.

3. There are a couple of examples in the example code for MASM32, you need to write an EXP file that has the exported procedures in it.
