xpfDecodeLogicalExpression

FUNCTION xpfDecodeLogicalExpression (expression         : STRING;
                                     decoded_expression : INTEGER;                

The xpfDecodeLogicalExpression function decodes a logical expression, where expression is the logical expression.  The decoded_expression argument is a handle to the decoded expression. The expression argument can be any legal logical EDMexpressX expression, including function calls, in source EDMexpressX format (ascii format). The returned decoded_expression argument is normally later used as argument in a xpxEvaluateLogicalExpression and xpfEvaluateLogicalExpression call.
