SYMPTOMS
========
On page 214, section 11.1.1, of the "Microsoft Macro Assembler 5.1 Programmer's
Guide", the documentation indicates that the equal sign (=) directive may be
used with expressions that evaluate to an address. However, if the address
refers to an external label, MASM 5.1 and 5.1a will generate the error:
error A2052: Improper operand type
MASM 6.0, 6.0a, and 6.0b will generate the error:
error A2026: constant expected
CAUSE
=====
MASM has a restriction that the (=) directive can not be used on an external
address.
RESOLUTION
==========
You can use the EQU directive to create an alias for an external address.
