Summary:
The module below demonstrates a problem with the Microsoft Macro
Assembler (MASM) versions 5.1 and 5.1a. If an EVEN directive is used
after an offset of 8000h within a segment, the assembler will try to
align the next instruction or data element on a 4-byte boundary. In
other words, more bytes for padding will be added than are necessary
to achieve even alignment.
Microsoft has confirmed this to be a problem in MASM versions 5.1 and
5.1a. This problem was corrected in MASM version 6.0.
