Handles file not found.
of CLEAR when entered with other
Restores registers for exit from DBSIFC. Clears handling of SVCs. Frees storage allocated for OS para.eter list.
Frees storage allocated for SVC si.ulation. Sets indication of first time tBSBEI is called.
Directs addition of ICC para.eter to OS para.eter list being
built for EREP. Handles the specification of an extra parameter on the CPEBEP co.mand line. Clears all error records from the error recording cylinders. Clears SRF frame records and all error records and refor.ats
the error recording cylinders. Writes CTlCRD inforllation inta SYSIN file
for EBEP to read.
Directs addition of HISi' paralleter to OS parameter list being
built for EREP. Directs addition of BERGE paralleter to OS parameter list being
built for EREP. Directs addition of BES and THRESHOLD parameters to OS parameter list being built for EREP. Directs addition of BDESUB para.eter to OS parameter list being
built for EBEP. Figure 11-2. DMSIFC and DMSREA label Directory (Part 1 of 2)

Description Writes SHARE parameter into SYSIN file for EREP to read.
Directs addition of ZERO parameter to OS parameter list being built for EREP. Checks CC portion of entered CCBOR for valid range.
Prepares for and issues DIAGNOSE command to read a page of
error records.
Prepares to read first record of next block.
Retains address of block just read into
buffer. Decides whether this block contains data or is empty.
Handles special considerations for ACC parameter Handles special considerations for HIST parameter
specification.
Restores registers and returns to caller from D!SREA. Sets error code for invlaid cylinder.
Handles end of cylinder indication.
Issues DMSFREE macro to get storage for
building OS parameter list.
Adds passed para.eters to OS parameter list
being built for EREP. Increments counters to step through buffer until e.Fty or end
of record found.
Reads and returns one line of control
parameters fro. the terminal or control file.
Handles errors reading control file from disk.
Handles calling subroutine to perform CLEIR. Figure 11-2. DMSIFC and D!SREA Label Directory (Part 2 of 2) Chapter 11. D!SIFC and DMSB!I--!BEP/Error Recording Interface 219
