Relational Operators
NOT, OR, and AND Operators and Condition Codes
If the root operator in the conditional expression of an IF statement is a relational
operator (<, =, >, <=, <>, >=, '<', '=', '>', '<=', '<>', '>='), pTAL sets the condition code
according to the result of the comparison.
Relational operators that test the condition code (for example, IF < THEN...) do not set
the condition code.
NOT, OR, and AND operators set the condition code indicator as described in
Section 13, Hardware Indicators.

Signed Relational Operators
Signed relational operators perform signed comparison of two operands and return a
true or false state.
Table 5-14. Signed Relational Operators
Operator Meaning Operand Type
*
Result
< Signed less than Any data type True/False
= Signed equal to Any data type True/False
> Signed greater than Any data type True/False
<= Signed less than or equal to Any data type True/False
>= Signed greater than or equal to Any data type True/False
<> Signed not equal to Any data type True/False
*
The data type of the operands must match except as noted in Data Types of Expressions
on page 5-2.
