expr

specifies a Boolean expression.

NOT

specifies the Boolean NOT operator. The backslash (\) is synonymous with

this operator.

AND

specifies the Boolean AND operator. The ampersand (&) is synonymous with

this operator. If you use the ampersand for AND, you may require a trailing

blank after the ampersand if it is followed by a word such as NOT and if the

ampersand is also the variable designator.

specifies the Boolean OR operator. The vertical bar (|) is synonymous with

this operator.

expr

specifies a Boolean expression.

(

expr

)

specifies a parenthesized Boolean expression.

test

specifies a test to apply to the Boolean expression.

IGNORE

specifies that the test for the following Boolean expression is to be ignored.

NCL returns a pseudo-result that must be either true or false, as defined

next.

TRUE

specifies that NCL provides a true result.

FALSE

specifies that NCL provides a false result.

ANY

for a Boolean expression that contains a list of left operands, specifies that

the test of the Boolean expression is true if any left operand passes the test.

Evaluation of the list stops once this condition is satisfied.
