About the slides

These class notes were originally presented at the Philadelphia Area Computer Society OS/2 SIG monthly meetings as part of our REXX initiative. They were prepared by SIG member Barry Mann using PPWizard and EPM. These notes are not intended to substitute for a formal REXX text or reference. They are provided as a convenience for those of us who lack a photo retentive memory.

How they were prepared

PPWzard is a REXX application that will run on any system supporting REXX. If you are maintaining a web site and feel maintenance issues are dragging you under, check out PPWizard -- especially now that you can use REXX!

The simple navigation bar at the bottom of each page would become an error prone nag if these pages were maintained by hand. Each month every page would need to be edited to reflect the new navigation bar content. With PPwizard on the job, a one line change will propagate throughout the site -- error free!

How easy is PPWizard to use? As always, your mileage may vary, but we recently inherited a 33 page site that was suffering the "it's a little too big to manage blues". They were using the same simple navigation bar that we have reused here, but it was falling apart with missing and mixed up links. There were several telephone number, mailing address, and other simple elements with formats that varied from page to page. We snipped off the tops and bottoms of all the pages, replacing them with PPWizard tokens and replaced all the phone numbers and addresses with PPWizard tokens. Even though this was our first encounter with PPWizard, we went from mess to tidy in about 8 hours -- including learning the basics of PPWizard.

About the solutions

We have provided a few solutions submitted by SIG members. Please note that these are not presented as "Model solutions", but are simply examples of how others approached a problem that may be stumping you. In some cases the solutions will not be complete or, in the opinion of the author, don't quite address the problem. Feel free to form your own opinion. "That's dumb, I'd never do it that way", or "Wow, why didn't I think of that?!", are both reasonable responses. In our opinion, this effort is structured as a learning experience and one often learns more while recovering from a mistake than as the result of an accidental success.
