z/VM: CP Commands and Utilities Reference - z/VM - IBM

1. Enter keyword parameters (if any).
2. Enter the ENDPARM keyword parameter.
3. Enter control statements (if any).
A comment card (*) may appear anywhere in the sequence above. The
TERMINAL operand is ignored if you enter it while using the prompting method.
v When you specify a keyword whose allowed values are Y and N, and you select
the value Y, you may enter the keyword parameter without specifying a value.
This form of the keyword parameter is always interpreted as a Y specification,
regardless of the normal default value.
v To begin CPEREPXA with system default values, respond to the first ENTER:
prompt message with the ENDPARM keyword parameter. When the second
ENTER: prompt message appears, respond to it by pressing the ENTER key
without any input; the null line signals to the system that there is no more input.
File Entry Method
The CPEREPXA command is entered followed by the file name, file type, and file
mode of a file that contains a “package” of EREP keyword parameters and control
statements arranged in the format as described in “Prompting Method” above. The
same rules regarding blanks, commas, and parentheses apply; in addition, card
images are truncated at column 71.
In practice, an installation probably has multiple files containing various operand
mixes to satisfy the installation CPEREPXA report needs. To create and generate
the necessary CPEREPXA files for this method of entry, use the CMS XEDIT
command. File generation using the CMS XEDIT command is described in z/VM:
XEDIT User’s Guide.
Mixed Method:
The CPEREPXA command is entered followed by the file name, file type, and file
mode of a file that contains EREP keyword parameters and control statements, one
of which is the TERMINAL operand of CPEREPXA. This operand may appear
anywhere in the file, and keyword parameters (if any) and control statements (if
any) are read until it is encountered. At this point, no further input is read from the
file. Prompting begins at the display station, where additional EREP keyword
parameters and control statements may be entered. When the system responds to
the TERMINAL operand by transferring control from the control file to the display
station, it expects input to proceed from the beginning of the sequence as it is
described in “Prompting Method” above.
CPEREPXA FILEDEFs
CPEREPXA
CPEREPXA issues the FILEDEFs listed below before invoking EREP. These allow
CMS to simulate the corresponding EREP files.
Where a mode letter of x is shown, x represents the read/write disk that has the
most free space when CPEREPXA is invoked. At the end of the run, the FILEDEFs
listed below are cleared with the exception of:
v EREPPT
v ACCIN
v ACCDEV.
These FILEDEFs are left intact because you can sometimes supply them yourself.
