SYNTAX:
 
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.
