Answer / guest

LDS is a VSAM dataset in name only. It has unstructured 4k
(4096 bytes) fixed size CI?s which do not contain control
fields and therefore from VSAM's standpoint they do not
contain any logical records. There is no free space, and no
access from Cobol. Can be accessed by DB2 and IMS fast path
datasets. LDS is essentially a table of data maintained on
disk. The 'table entries' must be created via a user program
and can only be logically accessed via a user program. When
passed, the entire LDS must be mapped into storage, and then
data is accessed via base and displacement type processing.
