Some programs need data in the LISTS,  ,before they will work. Some programs show results in the LISTS.
----------------------------------------------------------------------------------------------------------------------------- ------------------------------------ALLSET
Clears L1, L2, L3, and copies their contents into L4, L5, L6.
Clears TABLE.
Removes conflicts between graphs and plots.
Resets some default settings that other programs may change.
Notes: Use ALLSET anytime something seems wrong with your calculator.
After ALLSET, you may need to press  and turn on any function you plan to use.
