Elementary exercise: Put the numbers 1 to 10 into the stack 1) An elementary program: << 1 2 3 4 5 6 7 8 9 10 >> 2) Using for - next << 1 10 for i i next >> 3) Using start - next << 1 'm' sto 1 10 start m m 1 + 'm' sto next >> 4) Using dup << 1 'm' sto 1 10 start m dup 1 + 'm' sto next >> 5) Using rcl << 1 'm' sto 1 10 start 'm' rcl dup 1 + 'm' sto next >> If I write: << 1 m sto 1 10 start m m 1 + m sto next >> why this program is not correct?
