Solution 20889: Ranger Program Will Not Work with CBL/CBR App on TI-83 Plus Family Graphing Calculators with OS 1.19.

How can I enable the RANGER program to execute after upgrading the OS to version 1.19 on a TI-83 Plus family graphing calculator?

The CBL/CBR App is not a "true app", but a group of programs wrapped into an App.  There are some changes to memory management in the 1.19 OS which conflict with the CBL/CBR App. Because of this change, users will need to download and use the Vernier EasyData™ App.

If you prefer using the RANGER program instead of Vernier EasyData App you can transfer the RANGER program to your calculator.

The RANGER program can be downloaded from the attachement link on this page.
