7.7.7 Logical Operators (Unary)
Syntax: Logical NOT: !<operand>
Description: The ! (exclamation point) operator returns 1 (true) if the
operand is 0; otherwise, it returns 0 (false).
The operand can be any expression evaluating to an absolute
expression.
Example:
!(8<5) ; = $1 (TRUE)
7.7.8 Relational Operators (Binary)
Syntax:
Equal: <operand> = <operand>
<operand> == <operand>
Not equal: <operand> != <operand>
<operand> <> <operand>
Less than: <operand> < <operand>
Less than or equal: <operand> <= <operand>
Greater than: <operand> > <operand>
Greater than or equal:<operand> >= <operand>
Description: These operators compare the two operands and return 1 if the
condition is true or 0 if the condition is false.
The operands can be any expression evaluating to an absolute
expression.
Example:
3 >= 4 ; = 0 (FALSE)
label = 4 ; = 1 (TRUE) if label is 4,
; 0 (FALSE) otherwise
9 < $B ; = 1 (TRUE)
