Program Editing
There are various reasons why you might want to modify a program you have
stored in program memory, such as to correct a program that turns out to have
errors, or to insert new instructions (like O, ©, or ¦).
Using program editing, you can do such modifications without rekeying in an
entire program.
Changing an Instruction in a Program Line
To change a single instruction in program memory:
1. In Program mode, use Â, ‚, or t. to set the calculator
to the program line preceding the line containing the instruction to be
changed.
2. Key in the new instruction.
3. Return to Run mode.
For example, to change an instruction stored in program line 05, press
t.04, then key in the new instruction that is to be stored in program line
05. The instruction previously stored in line 05 will be replaced; it is not
“bumped” into line 06.
Adding Instructions at the End of a Program
To add one or more instructions at the end of the last program stored in program
memory:
1. In Program mode, set the calculator to the last (highest numbered) line
keyed into program memory.
2. Key in the new instruction(s).
3. Return to Run mode.
