Summary:
In the Macro Assembler (MASM) version 6.00, the percent character "%"
is not allowed in any identifier name. The valid characters that can
be used in an identifier are listed on page 13 of the "Macro Assembler
6.00 Programmer's Guide."
More Information:
The following is a possible error that may occur if you attempt to use
an identifier containing a percent character:
file.asm(6): error A2009: syntax error in expression
Because the percent character is also used as the expansion operator
(see page 238 of the "Macro Assembler 6.00 Programmer's Guide"), the
assembler will not accept the percent character in identifiers, even
in MASM 5.10 compatibility mode (selected by using the /Zm switch).
The Macro Assembler version 5.10 does not document the percent
character as being valid in identifiers, but it was accepted by the
assembler.
One workaround for this situation is to remove the percent character
from the identifier.
