Relational operators

Relational operators provide the means for comparing two items. A relational operator plus the items form a relation. An arithmetic relation is two arithmetic expressions separated by a relational operator, and a character relation is two character strings (for example, a character expression and a type attribute reference) separated by a relational operator.

The relational operators are:
EQ Equal
NE Not equal
LE Less than or equal
LT Less than
GE Greater than or equal
GT Greater than
