Meta-Assembler (MASM) Programming Reference Manual

MASM Usage
2-16
Example 4
$EQU
This is an invalid symbol if you try to insert it into the dictionary. It is a valid symbol if
you are referring to the MASM directive $EQU.
Example 5
A/B
This is an invalid symbol, but it is a valid expression.
Example 6
2.3.3. Fields
AVERYLONGNAME
This is a valid MASM symbol, but is the same as AVERYLONGNAM because MASM
accepts only 12 characters.
The functional part of a MASM statement consists of the following fields:
Label
Operation
Operand
2.3.3.1. Label Field
This field is optional and is used to introduce symbols into the dictionary. The label field
can be divided into subfields. These subfields can be further divided into items. The
following entries are allowed as items, in the order given:
1. Page control
The first item can be a slash (/) to indicate page eject.
2. Line levelers
The next item on the line can be a line leveler in the form %n, where n is an unsigned
integer (see 6.9).
3. Location counter specifications
The leveler can be followed by a location counter specification in the form $(e),
where e is an expression evaluated as an integer in the range of 0 to 63.
