QSAM stands for -- Queued Sequential Access Method. This is an extended version of the basic sequential access method (BSAM). When this method is used, a queue is formed of input data blocks that are awaiting processing or of output data blocks that have been processed and are awaiting transfer to auxiliary storage or to an output device.
Flat file, on mainframes, is loosly used to refer a QSAM file.
ISAM stands for Indexed Sequential Access Method. This is an access method that can be used for either direct or sequential update or retrieval. An index is stored on DASD with the data set. _________________ Regards,
