NCPDUMP Service Program and How To Use It NCPDUMP is a CftS command. It processes CP spool reader files created by 3705 du.ping operations, that is, dump files that are produced as a
result of the CP NETWORK co.mand specified with the DUftP operand and
either automatic or immediate mode.
The NCPDUMP file processing operation can include: • Erasing a specific CMS BCPDUMP file after printing it. • Formatting the dump. • Printing the dump. • Assigning an identifier to the CMS NCPDU8P file. • Creating the CMS BCPDUMP file from the spool file.
Although HCPDUMP is a efts command, its use is restricted to the user
identified by the SYSDUMP operand of the SYSOPER macro in DftKSYS during V8/370 system generation. The operation of HCPDU8P is similar to V8FDUMP operations. A general description of the BCPDUMP operation
follows the co.mand description.
The NCPDUMP command has the following format: NCPDUMP I [DUMPxx] [ ([ERASE][NOFORM](MBEMOHIC][BCPBUFF][) ]] DUMPxx ERASE NOFORl! is the filename of a CMS file containing a 3104/3105 Communications Controller program dump. This dump was created by a previously invoked HCPDUMP com.and with the ERASE operand
not specified.
erases the current CP DUMP file or a specified (filename), saved CKS file.
specifies that a formatted control block is not desired. MNEMONIC includes 3705 Assembler mnemonic operation codes in the
printed output. ICPBUFF specifies that a formatted listing of the KCP buffer pool is
desired.
The NETWORK command invoked with the DUMPxx operand, as stated
previously, produces CP files that contain the contents of a designated
3704/3705 Communications Controller unit buffer. These CP files reside
as a spooled reader input assigned to a system-designated user. The CftS ICPDUMP command invoked by this user formats (if requested) and prints
the contents of these files.
The NCPDUKP program creates a C!S file with a filename DUftPxx and a
filetype of NCPDUMP, and erases the original sIooled NETWORK initiated dump reader file. The created CMS file is erased if you specify ERISE; otherwise it is kept.
A maximum of ten du.ped spooled files can be processed and saved, and
later recalled, if necessary, by the system assignment of an xx identifier suffix to the CKS DUMPxx filename. The "xx" is a decimal number from 00 to 09, depending on any existing files of a similar na.e.
For example, if the files DUMPOO ICPDUMP and DUMP01 NCPDUMP already Section 4. VM/370 Service Programs 199

exist, the new file would be called DUMP02 NCPDUMP. The file thus
created is retained for later use unless the ERASE option is specified,
in which case the file is erased immediately after the dump is printed.
ZAP Service Program and How To Use It ZAP is a CMS command that modifies or dumps MODULE, L01DLIB, or TXTLIB files. It may be used to aodify either fixed or variable length ftODULE files. It is for use by system support personnel only.
Input control records control ZAP processing. They can be subaitted
either from the terminal or froa a disk file. Using the VER and REP control records, you can verify and replace data or instructions in a
control section (CSECT). Using the DUMP control record, you can dump all or part of a CSECT, or an entire member of a LOADLIB or TXTLIB file,
or an entire module of a MODULE file.
The format of the ZAP co.mand is: ZAP LOADLIB (libname1 ••• libname3X (option ••• ()]] {
MODULE } MODULE L01DLIB TXTLIB libname TXTLIB .Ql!!ion§: r , r , IIPRINT I IIBPUT filenameilHOPRINTI L .J L .J
indicates the type of file that is to be modified or duaped.
is the library name contain-ing the meaber to-be .odified or duaped. You can specify one to three library naaes. The libname is valid only for L01DLIB and TXTLIB files.
r , !!RM IPRINT I INOPRINTI L .J
indicates that input to the ZAP service program is subaitted
through the terminal. If you specify TEB!, the prompting
message ENTER: is issued, and you can then enter input control
records up to 80 characters long. If you specify PRINT ¥ith all output prints on the printer, but only error
aessages display at the terminal. If you specify ROPRINT with TERM, nothing prints on the printer. All output except
control records displays at the terminal. r , INPUT filename IPRINT I I NOPRINT I L .J
specifies that input is submitted from a disk file, 200 Vft/370 Operator's Guide
