Undefined-length records when using LBI or for fixed-length blocked: The method described in the following paragraphs can be used to calculate the block length. You can use this method with BSAM, BPAM, or BDAM. (It should not be used when using chained scheduling with format-U records. In that case, the length of a record cannot be determined. After issuing the CHECK macro for the DECB for the READ request, but before issuing any subsequent data management macros that specif If you are using LBI for BSAM or BPAM, subtract 12 from the address of the status area. This gives the address of the 4 bytes that contain the length of the block read.
