CPT5.DOC Page 2 CHKPNT.DOC -- Changes from V4(113) to V5(116) October 1981 1.0 SUMMARY CHKPNT has three major functions: 1. Compile account statistics on disk space utilization. 2. Set the monitor checkpoint interval. 3. Copy system-generated accounting data to the accounting file. CHKPNT version 5(116) runs only on Release 5 of TOPS-20. CHKPNT is documented in the TOPS-20 Operator's Guide. 2.0 EXTERNAL CHANGES It is possible for CHKPNT to suffer column overflow while doing a NOUT for certain records. This error is not fatal, and CHKPNT continues processing records; only the data in the overflowing field will be suspect. However, an annoying repetition of the message "Column overflow ..." results. The error reporting mechanism has been changed such that the column overflow message is typed only once, followed by the number of occurrences detected. 3.0 KNOWN BUGS AND DEFICIENCIES There are no known bugs or deficiencies. 4.0 INSTALLATION INSTRUCTIONS 4.1 Files Needed to Run CHKPNT CHKPNT consists of one file, CHKPNT.EXE CPT5.DOC Page 3 4.2 Instructions for Loading and Installing CHKPNT Mount the tape labeled Installation Tape on MTA0: and type the following commands: SKIP MTA0:5 FILES R DUMPER TAPE MTA0: REWIND DENSITY 1600-BPI SKIP 1 RESTORE <*>CHKPNT.EXE (TO) SYS:*.*.-1 REWIND 4.3 Files Needed to Build CHKPNT CHKPNT is built from the following file: CHKPNT.MAC In addition, the following files must be on SYS: MACREL.REL MACSYM.UNV MONSYM.UNV ACTSYM.UNV 4.4 Instructions for Building CHKPNT Mount the tape labeled Distribution Tape on MTA0: and type the following commands: R DUMPER TAPE MTA0: REWIND DENSITY 1600-BPI SKIP 1 RESTORE <*>*.*.* (TO) <self>*.*.* REWIND ^C SUBMIT CHKPNT.CTL/TIME/UNIQ:0/REST 4.5 Special Considerations None.
