NAME : HCPSCGBK
DESCRIPTION: 64 byte Subchannel Measurement Block
DSECT : SCGBK
FUNCTION : The measurement block is an architectually defined
64 byte area that contains the accumulated values
of the measured parameters for each subchannel.
LOCATED BY : RDEVMBLK field of RDEVBK - logical address of
measurement block
CREATED BY : HCPCHMGS when subchannel measuring is turned on for a device
DELETED BY : HCPCHMRS when subchannel measuring is turned off for a device
COMPATIBILITY AND MIGRATION CONCERNS : HCPSCGBK describes the 64 byte subchannel measurement block.
HCPSCMBK describes the 32 byte subchannel measurement block.
When changing this control block, check if HCPSCMBK also
requires changes.
RELOCATION CONSIDERATIONS : None
NOTES : ABNORMAL coded because the block is updated by
hardware asynchronously. The PL/X compiler may not
make any assumptions during optimization about the
data contained in this block.
