CPF was added in MVS 4.1.0 (if I recall correctly) - many years after the advent of the SSI. I wrote big chunks of the SVC 34 processing for CPF (back in the 80s...). There is nothing in the operating system, nor the SSI, that forces a subsystem to declare or use a prefix. Also, there is nothing requiring an invoker of the Command Prefix Facility actually be a subsystem. Any program that meets the authorization requirements can do so. Additionally, CPF supports command prefixes that are greater in one character in length. There is an example in the doc that shows how to programmatically set up a prefix that automatically routes a command to execute on a particular system, so you don't have to use the ROUTE command. http://pic.dhe.ibm.com/infocenter/zos/v2r1/index.jsp?topic=%2Fcom.ibm.zos.v2r1.ieag300%2Fmccpf.htm Scott Fagen Chief Architect - System z and Workload Automation CA Technologies ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
