Assign local variable inside for/start loop
I tried to calculate pi with Gauss - Legendre algorithm. So this program input repetition count. there is program code below.
Code: << 1 2 √ INV 4 INV -> N A B T << Of course, I can assign global variable like 'A' STO, but I want to use local variable. Can't I assign a local variable inside a loop? S.Korean / HP-50G | fx-570EX | fx-570CW | HP-200LX |

RE: Assign local variable inside for/start loop
How about using a compiled local variable?

RE: Assign local variable inside for/start loop
Since A, B and T already exist as local variables, don't create them again; just use STO as usual to store the new values into them. Replace the second -> A B T with something like 'A' STO 'B' STO 'T' STO (or in the opposite order, depending on the order that they are in the stack). This will store the desired values into the local variables, not into global ones. Also, note that after the inner program ends, those variables will cease to exist, so access them if needed immediately after the NEXT command.
