And if you're looking for a supported product that's easy to use and has additional functions, take a look at Operations Manager for z/VM (http://www.ibm.com/software/sysmgmt/zvm/operations/index.html)
For the scheduling function, look at the DEFSCHD command on page 54 (in Chapter 6) of the Installation and Administration Guide available at: http://www.ibm.com/software/sysmgmt/zvm/operations/library.html Tracy Dean, IBM
