RE: 15C functions that can be cancelled with 'null' (quiz)
I can only find 5 generic operations, but I'm counting 90 key sequences.
Compare page 173 of the Owner's Handbook. Code: 6 STO A..E, (i) FIX, SCI, ENG, as well as SF, CF, F? throw "Error 1" if a matrix descriptor is in the index register. I can't find anything that's not related to matrices. Program-related operations that display the instruction while the key is being pressed (R/S, SST, BST, SOLVE, ∫) don't have the "null" cancelation. |
