This blog has been neglected lately because of vacations and travel, but I must add an entry for today (August 2, 2012) to wish VM a happy birthday! The VM product was announced on August 2, 1972 with VM/370, so today is when we consider VM to be "born". More information about the anniversary (ok, more people refer to today as its anniversary date and not its birthday) can be found at http://www.vm.ibm.com/vm40bday.html.
On the subject of web pages, I hope you're familiar with the VM home page (http://www.vm.ibm.com). It is the place you should go to find out more information about z/VM and its related products. Be sure to use the search facility found on the sidebar on the right (named Site Search). This is the easy way to find the web page you need.
The other page on the VM web site that I really like is the Downloads page (http://www.vm.ibm.com/download/). This has a bunch of user written tools and utilities (457 of them today) that you can download and use. (Select the "packages page" link to see the list.) Even if you can't find a specific package that does what you're looking for, you may find some ideas in other packages that are on that page.
