names grouped by application type, and the list is not alphabetized. This makes it tedious to determine

[1.4] Importing and exporting PC data with the TI-89 / TI-92 Plus

It can be useful to move data between a PC and the calculator. For example, you might want to make
better data plots with a PC graphing program, from calculated results. Or you might want to download
a large data set to the calculator for processing.
These suggestions apply to Windows PCs. Some tips for Mac follow.
Unfortunately, transferring data from a PC to the calculator is quite limited. There are only two types of
data you can transfer from the PC to the calculator: text variables, and numeric matrices.
