VAL2

,

VAL3

,

and

VAL4

can also be character strings (enclosed in quotes) or

Oper

= EQ and NE only.

Oper1

Operation label. A tolerance of 1.0E-10 is used for comparisons

between real numbers:

EQ --

Equal (for

VAL1

=

VAL2

).

NE --

Not equal (for

VAL1

≠

VAL2

).

LT --

Less than (for

VAL1

<

VAL2

).

GT --

Greater than (for

VAL1

>

VAL2

).

LE --

Less than or equal (for

VAL1

GE --

VAL2

).

Greater than or equal (for

VAL1

ABLT --

VAL2

).

Absolute values of

VAL1

and

VAL2

before < operation.

ABGT --

Absolute values of

VAL1

and

VAL2

before > operation.

VAL2

Second

numerical

value

(or

parameter

which

evaluates

to

a

numerical

value) in the conditional comparison operation.
