Expression Evaluator Functions
B Expression Evaluator Functions
The expression evaluator is a system procedure used by the user interface to accept a
string, number, or Boolean expression, evaluate it, and return the result. This procedure is
used by the CALC, SETVAR, IF, ELSEIF, and WHILE commands and within a ![ ]..
The expression evaluator provides the following:
• consistent evaluation of expressions
• compatibility with MPE V/E job control word evaluation
• user flexibility
The expression evaluator uses algebraic notation and supports the functions defined in
Table B-1. The references that appear in this table in parentheses, for example (8), are
defined following the table.
See HELP for description of new functions and examples.
