xpxDecodeLogicalExpression

 
SYNTAX:
 
xpxDecodeLogicalExpression(expression             : STRING;
VAR decoded_expression : INTEGER) status                 : INTEGER;
 
The xpxDecodeLogicalExpression 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 EDMexpressX^format (ascii format).
The returned decoded_expression argument is normally later used as argument in a xpxEvaluateLogicalExpression call.
