Hi Guys


I am fairly new at assembly languages and I need to learn how to do a simple program

what it would do is take 3 stacks, one with three characters and one with  numbers 1-3(in random order) and the third one would be empty.

Basically I want to make a program that takes the letter from the first stack and check its number on the second stack and essentially put it in that order on the third stack

So for example if the character was B and the number was 2 then B would be BETWEEN the two other characters at the end of the script.

so assume the stacks were like this (before the program)

Stack 1   Stack 2    Stack 3(empty)
  B         1        -
  A         3        -
  D         4        -
  E         5        -
  L         2        -  

After the program stack 3 would look like this

Stack 3
  B
  L
  A
  D
  E

It would be nice if stacks A and B were not effected

And it does not necessarily have to be a letter as long as all the data in stack A is the same size.

I know this might be much but it would really help me a lot.


thanks.

I hope it works!

iterate trough stack and find a match ex. for number 1
        la r4,1
        la r5,stack2
        la r6,0
        la r7,stack1
        sr r5,r7
        lr r7,r5
        la r5,stack2
loop    c  r4,0(r6,r5)
        be tost3
        la r6,1(r6)
        b  loop
tost3   la r9,stack3
        ar r9,r6
        ar r6,r5
        sr r6,r7
        mvc 0(0,r9),0(r6)
        la  r6,0
        la  r4,1(r4)
        c   r4,stklen
        bnh loop
        l  r13,save+3
        return (14,12)
stack1 dc  al1(c'b',c'a'....)
stack2 dc  a(x'000001',x'00000003'...)
stack  ds  Xal1        x is the number of elements in stacks
stklen dc  x'XY'    xy=num of elemetts in hex
       yregs
       end
