Problem:
The OUT/IN instruction in MASM should be flagged as invalid opcode
when EDX is used instead of DX. MASM also fails to check for DL
register (with or without .386).
Response:
This problem was fixed in MASM Version 5.00A. Please call Product
Support and request an update to MASM Version 5.00A.
