Notes:
1. Outermost expression must be enclosed in parentheses in SETB and AIF instructions.
2. Optional parentheses around terms and expressions at this level.
| 3. Must be in the range 0 through 1024 characters.
4. Must stand alone and not be enclosed in single quotation marks.
Figure 101. Defining Logical Expressions
Subscripted SETB Symbols
The SETB symbol in the name field can be subscripted, but only if the same SETB
symbol has been previously declared in a GBLB or LCLB instruction with an
allowable dimension.
The assembler assigns the binary value explicitly specified, or implicit in the logical
expression present in the operand field, to the position in the declared array given
by the value of the subscript. The subscript expression must not be 0 or have a
negative value.
