With the help of the kind folks at the Usenet newsgroup comp.​infosystems.​www.​authoring.​html, particularly Jukka Korpela, I am updating every page on the site to meet modern standards:

I started these changes in mid-October and finished them in mid-November — except for italicizing variable names, which is still in progress. You may not notice any of these changes, but if you do see anything wrong, please tell me about it.

The MATH200B program didn’t display well with the new color TI-84 models, TI-84 Plus C Silver Edition and TI-84 Plus CE. I first created separate programs for the new calculators, but that was a dead-end approach.

Both MATH200B and MATH200A now sense whether they’re running on a high-resolution TI-84, and adjust their display format accordingly. Sometimes that even lets one screen hold the information of two screens on the older calculators.
