>There is a pretty slick way to keep lists on the TI-82/83. Suppose you have two lists in L1 and L2. While the data is still there, go to the program editor for a new program, give the program a name that makes sense to the data, and on the first line, enter the following: RCL (2nd STO) L1 enter STO L1 enter. Do the same on the next line for L2, and continue for any other lists you may have for that data set. Once you are done, you can clear out those lists, then when you want the data back, simply run the program. ------------------------
I just converted many of my TI-83 group files into program files as per Bill's suggestion. What a great idea!! There are great advantages:
1) The programs take less storage than keeping the lists as lists in the calculator. 2) Data sets that have more than one list can be grouped together under the program name which can be the same as the files supplied by publishers on disk. Data sets with identical list names (such as YEAR) will not conflict when loaded into the calculator. 3) There are some "features" of the new TI-83 Graph Link which makes it more difficult to transfer Grouped Data Lists than it does a program file. 4) My programs general format for the TI-83 is similar to the following example:
In this way, when the program is executed, the lists the students want to see (DIST and FARE) in the Stats Edit Window show up automatically while other lists are not displayed.
5) It should be noted that you cannot convert TI-83 programs to TI-82 programs, so those who are working in a mixed environment (TI-82 & TI-83) probably want to create your data programs in the TI-82 and then upload to the TI-83.
