*SAME: The value does not change.
lines-per-page: Specify the number of lines per page. Valid values range from 1 through 112.

Forms type (FORMTYPE)

Specifies the form type of the default printer form which is used for System/36 printouts when no form type is specified in the SET command or in the FORMS or PRINTER OCL statement. The form types used to indicate different printer forms are user-defined and can be a maximum of 4 characters in length.

*SAME: The value does not change.
*STD: The standard form type is used.
form-type: Specify a user-defined form type.

Default message action (DFTMSGACN)

Specifies the default action used for escape messages issued by CL commands in procedures running in the System/36 environment. The default action is used for messages not in the message list and when there is no message list. The default action is not used if the message list contains a message ID.

*SAME: The value does not change.
*CONTINUE: Processing continues with the next statement after the CL command. The ID of the escape message is saved and can be retrieved by the message ID substitution expression (?MSGID?).
*HALT: The procedure is stopped. Processing continues as specified on the Halt options (HALTOPT) parameter.
*IGNORE: The error is ignored and processing continues with the statement after the CL command. The ID of the escape message is not saved.
*CANCEL: The procedure is canceled.

Halt options (HALTOPT)

Specifies a list of continuation options available when *HALT is specified for the default message action parameter. The list of options is a value consisting of up to 4 options with values ranging from 0 through 3, each of which represents an allowed response. If no options are specified, options 0 and 3 (value 03) are allowed. The meanings for the numbers assigned to the options are:

0: Continue. The message ID is saved for retrieval.
1: Retry the command. The message ID is not saved.
2: Cancel the job step. The message is saved for retrieval.
3: Cancel the job.

*SAME: The value does not change.
halt-options: Specify up to four continuation options. Multiple options must be specified in ascending order and each option must be unique. Each digit must be the character 0, 1, 2, or 3 (blanks are ignored).

Evoke storage pool (EVKJOBPOL)

Specifies the storage pool used for an EVOKE job that bypassed the job queue when starting to run in the System/36 environment.

Evoke job priority (EVKJOBPTY)

Specifies the priority level at which an EVOKE job in the System/36 environment must be started when it bypasses the job queue.

*SAME: The value does not change.
*SUBMITTER: The job is started with the same run priority as the submitting job.
1-99: Specify a priority level.

Source file record length (SRCRCDLEN)

Specifies the record length in bytes for System/36 source files QS36PRC and QS36SRC. These source files are created by System/36 environment utilities.

*SAME: The value does not change.
record-length: Specify the source file record length. Valid values range from 40 through 120 bytes (not including the extra 12 bytes required for the source sequence and date fields of each record).

Allow CHGS36 while active (CHGACT)

*SAME: The value does not change.
*YES: The configuration information can be changed with the CHGS36 command while others are signed on to the System/36 environment.
*NO: The configuration information cannot be changed with the CHGS36 command while others are signed on to the System/36 environment.

Add only S/36 users (ADDS36ONLY)

Specifies whether a workstation device can be added to the System/36 environment configuration when the device signs on to the System/36 environment.

*SAME: The value does not change.
*YES: A workstation device is added to the configuration only when that device signs on to the System/36 environment.
*NO: A workstation device is added to the configuration when that device is created, not when it signs on to the System/36 environment.

Substitute ICF procedure data (ICFSUBST)

Specifies if data received on an intersystem communications function (ICF) start request is scanned for substitution expressions.

*SAME: The value does not change.
*YES: The data received on an ICF start request is scanned for substitution expressions, unless it is an ICF start request from a retail device or a finance device.

Examples

CHGS36A   FLIB(MYLIB)  CACHEDLTF(*YES)  LPPAGE(66)
