When you read a post for a program, I will say "Create a new program, and name it..." This will be the article referred to, if you have no clue what I mean. Alrighty roo, here we go:
Press the "prgm" button (4th button down, 3rd across)
Press the left arrow until you are on the "NEW" tab
Press enter on "1:Create New"
Enter the name stated in the tutorial
This is the steps taken on most TI calculators, unless you have any version of the nSpire. If anyone wants a tutorial for that, drop a comment below.
Thanks!
