| Notes:
| 1. If a √ is in this column, the function is available in the “logical-expression” format.
| 2. If a √ is in this column, the function is available in the “function-invocation” format.
| 3. Possible values in these columns are:
| A Arithmetic
| B Binary
| C Character
| 4. For these functions, the maximum length of the operand (and output) is the maximum
| string length that the assembler supports, currently 1024.
Arithmetic (SETA) Expressions
Figure 100 shows how arithmetic expressions can be used.

AIF
(&A1 GT 3).A

Sublist notation Subscript Given sublist (A,B,C,D)
named &PARAM,
if &A=1 then &PARAM(&A+1)=B

When an arithmetic expression is used in the operand field of a SETC instruction
(see ▌1▐ in Figure 100), the assembler assigns the character value representing
the arithmetic expression to the SETC symbol, after substituting values (see ▌2▐ in
Figure 100) into any variable symbols. It does not evaluate the arithmetic
expression. The mathematical sign (+ or −) is not included in the substituted value
