Conditional Operators
Operator Condition Tested
EQ Equal
NE Not equal
GT Greater than
LT Less than
GE Greater than or equal
LE Less than or equal
A condition is programmed between the [ and ] brackets in the following
format:
[A EQ B]
where:
- A and B represent some numerical value
- the values for A and B are in the form of some mathematical equation
or in the form of a paramacro parameter
Example 20.6 illustrates the use of the conditional operators found in
Table 20.C.

Evaluation of Conditional Expressions
Expression Evaluation
[6.03 EQ 6.0301] FALSE
[6.03 NE 6.0301] TRUE
[2.5 GT 2.5] FALSE
[2.5 LT 2.51] TRUE
[2.51 GE 2.5] TRUE
[2.5 LE 2.5] TRUE
[[2.5-3] LE 1] TRUE
[#1 GT #2] This depends on the value of the parameters #1 and #2
For details on the use of conditional expressions, see page 20-9 for details
on “IF” statements and page 20-11 for details on “WHILE” statements.
