| If I understood you correctly... search for PUSH,PULL,QUEUE, Newstack, Delstack.... in the Rexx manual. |

Hi.
By this way you can push the variable into stack in rexx and also access them individually
| Code: |
Push ABC /* puts ‘ABC’ in top of stack */
Push stpaul /* puts ‘stpaul’ over ‘ABC’ */
pull data /* pulls data from the top of stack */
say ‘from the stack ‘ data /* displays ‘stpaul’ */
pull data /* pulls data from top of stack */
say ‘from the stack ‘ data /* displays ‘ABC’ */
pull data /* obtains input from tso terminal */ |

You can't get a value directly from the middle of the stack; you have to read the stack sequentially.

Ofer,
To get the values directly from the middle of the stack.
I think we need to create a new stack.
Correct me if i am wrong.
| Code: |
"NEWSTACK" /* creates new stack */
Push CTS /* puts ‘CTS’ in top of stack */
Push stpaul /* puts ‘stpaul’ over ‘CTS’ */
pull data /* pulls data from the top of stack */
say ‘from the stack ‘ data /* displays ‘stpaul’ */
pull data /* pulls data from top of stack */
say ‘from the stack ‘ data /* displays ‘CTS’ */
pull data /* obtains input from tso terminal */
"DELSTACK" /* delete stack */ |

Sure, you can create a new stack for each item....  .... but i don't think this is a good programming practice (not to mention resources and performance).
