Parameters for Optional Interfaces for Separately Licensed Features › IMS-related (IOF) Parameters › IMSnCHAR Parameter

IMSnCHAR Parameter

Defines the command character for an IMS control region that CA OPS/MVS processes through its IMS Operations Facility (IOF). The n value is the region number. CA OPS/MVS allows up to 32 IMS control regions in the IOF, each having its own unique command character.

By prefixing the IMS command with this command character, you can send a command to the n IMS region without using a REPLY command. CA OPS/MVS automatically determines the WTO request of the IMS region and responds to it with the intended command.

Important! The IMSnCHAR parameter can only contain characters from the table shown in Characters That Can Be Used In z/OS Commands in the chapter “Using This Reference.” This parameter may be set to a single or double quote (x'7D' or x'7F') by supplying the value as a hexadecimal.

Note: This parameter does not modify the IMS CMDCHAR value defined in the IMS system generation. It is only used as an alias value, to allow an operator to issue a command to IMSn without knowing the IMSn WTOR replyid.

Default values

• The / character

  This value is for IMS regions 1 through 32.

• A blank

  This value is for IMS regions 2 through 32.

Other possible values

Any character, as long as each IMS region has a different command character
