Special host application (SPCHOSTAPP)

Specifies whether SNUF customizes support for special host applications outside the Customer Information Control System for Virtual Storage (CICS/VS) or Information Management System for Virtual Storage (IMS/VS) application layer.

*SAME: The value does not change.

*NONE: SNUF does not customize support for special host applications.
*FLASH: SNUF customizes support for the Federal Reserve Flash application.

Host type (HOST)

Specifies the type of host system with which the device will communicate.

*SAME: The value does not change.

*CICS: The host system type is CICS/VS.
*IMS: The host system type is IMS/VS.
*IMSRTR: The Information Management System is the host system. RTR (return-to-ready) commands will be used in communicating with the host system.
*ADCS: The Advanced Data Communications for Stores is the host system.

Record length (RCDLEN)

Specifies the maximum record length allowed when communicating with this device.

Valid values range from 1 to 32767.

The value must be at least the size of the largest record to be sent, but must not exceed the buffer size specified on the line description (MAXBUFFER parameter) to which this device is attached.

*SAME: The value does not change.

Block length (BLKLEN)

Specifies the maximum block length allowed when communicating with this device.

The possible values are from 1 to 32767.

The value must be at least the size of the largest record to be sent, but must not exceed the buffer size specified on the line description (MAXBUFFER parameter) to which this device is attached.

*SAME: The value does not change.

Default program (DFTPGM)

Specifies the name of the program called if a program start request is received and no program is specified.

The program is specified by its qualified name (library-name/program-name).

*SAME: The value does not change.

The possible library values are:

*LIBL: All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB: The current library for the thread is searched. If no library is specified as the current library for the thread, the QGPL library is searched.

library-name: Specify the library where the object is located.

HCP emulation (HCPEML)

Specifies the Host Command Processor (HCP) emulation to be performed.

*SAME: The value does not change.

3651: The host is running ADCS and will use this device description for a 3651 HCP emulated session.
3684: The host is running ADCS and will use this device description for a 3684 HCP emulated session.
4680: The host is running ADCS and will use this device description for a 4680 HCP emulated session.
4684: The host is running ADCS and will use this device description for a 4684 HCP emulated session.
*STRUSRPGM: The host is running ADCS and will use this device description for the Start User Program (SUP) emulated session.

Examples

CHGDEVSNUF   DEVD(SNUFDEV01)  PGMSTRRQS(*YES)  DFTPGM(INQUIRY)

This command changes the device description for communications device SNUFDEV01, reserving it for host system call by the use of a program start request. The default program is changed to INQUIRY.
