ERROR( )
The ERROR procedure returns a string containing a description of any error that was posted. If no error was posted, ERROR returns an empty string. You should interrogate ERROR immediately after the statement which you suspect may post an error because processing any other statement which could post an error will clear the internal errorcode.
| Return Data Type: | STRING |
Example:
PUT(NameQueue) !Write the record
IF ERROR() = 'Queue Entry Not Found' !If not found
ADD(NameQueue) !add new entry
IF ERRORCODE() !Check for unexpected error
STOP(ERROR())
END
END
