LCRBK Control Block Content

Hex Dec Type/Val Lng Label (dup) Comments ---- ---- --------- ---- -------------- -------- 0000 0 Structure LCRBK Locate Record Parameter 0000 0 Bitstring 1 LCROPER Operation byte 0001 1 Bitstring 1 LCRAUX Auxiliary Byte LCRCMNSK is not actually a field in the LCR parm list. It is used by HCPFTR to address the SEEKA field in a way that allows use by routines that expect to see 00CCHH. These routines only deal with the CC portion so it does not matter what is actually in the first 2 bytes. 0002 2 Bitstring 1 LCRCMNSK Address of "SEEK" 0003 3 Bitstring 1 LCRCOUNT Record/track count 0004 4 Bitstring 4 LCRSEEKA Seek address: CCHH 0008 8 Bitstring 4 LCRSRCHC Search address: CCHH 000C 12 Bitstring 1 LCRSRCHR Search address: R 000D 13 Bitstring 1 LCRSECTR Sector address 000E 14 Bitstring 2 LCRXFRLN Transfer Length Factor .... ..11 LCRACCES X'03' Mask to check authorization 11.. ....
