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 ••• ()]] {

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

control records displays at the terminal. r , INPUT filename IPRINT I I NOPRINT I L .J

com.ands and control records in error and error messages display at the terminal. If you specify NOPRINT with IIPUT filename, nothing prints on the printer. All output displays

Eight types of ZAP control records exist: DU!P, IA!E, BASE, VER or VERIFY, REP, LOG, COft8EIT, and END. ZAP control records are free-form and need not start in position one
of the record but the ZAP program can accept only 80 characters of data
for each control record. Separate all information by one or more blanks. All address fields including disp (displacement) fields in VER and REP control records must contain an even number of hexadecimal digits, to a maximum of six digits (OD, 02C8, 014318). Data fields in VER and REP control records must also contain an even number of
hexadecimal digits, but are not limited to six digits.

The program sets the ROGO switch on if a control record is found to be in error. A file cannot be modified once the ROGO switch is turned
on. The next valid BA!E record turns the lOGO switch off. This means
that if the control record is the IA!E record, all succeeding records
are ignored until the next BAME, DUMP, or Elt record. For any other
error, only REP control records that follow are ignored.
The DU!P control record resets the ROGO switch off. The DU!P record must not immediately precede a BASEl VER, or REP control record.
A IA!E control record must precede the BASE, VER, and REP control
records (if any) that follow a DUMP control record. Section 4. V8/370 Service Programs 201
