xpxDecodeLogicalExpression

FUNCTION xpxDecodeLogicalExpression(expression             : STRING;
                                    VAR decoded_expression : INTEGER) 
                                    status                 : INTEGER;

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