OUT/IN Invalid with EDX ID Number: Q26810
5.00 MS-DOS buglist5.00
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.
