David, Calling the ModifyProp() and/or NewModifyProp() functions from a C program require that all arguments be 32-bit (long) values. Calling them from an Assembly program also require that 32-bit values be passed (since each argument is in a separate register). However, the functions are documented in the AutoDocs (which should be treated as semi-gospel) indicate that the Pot and Body values are USHORTs, which means they're unsigned 16-bit values. They're definitely not 1-byte parameters (8-bit). Hope this helps….BobR
