Return:
Return code field set
Note: Btrieve sets low byte of vector to 33h; this serves as the installation check

Notes: Add 50 (32h) to any "get" operation to just return the key data. Add 100 (64h) for a single-record wait lock (automatically released on next get). Add 200 (C8h) for a single-record nowait lock (nowait lock returns error 54h or 55h if record already locked). Add 300 (12Ch) for a multiple-record wait lock (not released until unlock called). Add 400 (190h) for a multiple-record nowait lock (nowait lock returns error 54h or 55h if record already locked)
