Summary:
SYMPTOMS
When using the Microsoft Macro Assembler (MASM) version 6.0, the
online help contains a documentation error when describing how to
detect an extended keyboard. The entry reads:
0000:0496 1 word If bit 5 set, indicates extended keyboard
installed.
In general, the "Microsoft Macro Assembler Programmer's Guide" for
version 6.0 refers to the low order bit as bit 0. Therefore, the
user is led to believe that if the bit corresponding to decimal
value 32 is set (bit 5), then there is an extended keyboard
installed.
RESOLUTION
The bit that should be checked is the one corresponding to decimal
16, or bit 4.
