NOMEMO(file)
| NOMEMO | Arms “memoless” record retrieval. |
| file | The label of a FILE. |
The NOMEMO statement arms “memoless” record retrieval for the next GET, REGET, NEXT, or PREVIOUS statement encountered. The following GET, REGET, NEXT, or PREVIOUS gets the record but does not get any associated MEMO or BLOB field(s) for the record. Generally, this speeds up access to the record when the contents of the MEMO or BLOB field(s) are not needed by the procedure.
Example:
SET(Master)
LOOP
NOMEMO(Master) !Arm “memoless” access
NEXT(Master) !Get record without memo
IF ERRORCODE() THEN BREAK.
Queue = Mst:Record !Fill memory queue
ADD(Queue)
IF ERRORCODE() THEN STOP(ERROR()).
END
DISPLAY(?ListBox) !Display the queue
