Hey,
I have a REXX that reads LISTFILE into program stack. So there are 1000 items in the stack and I am iterating and pulling from it until it is empty. But now i have some items where I need user feedback. So I tried to do
| Code: |
Say 'You need to keep this file?' filename
pull answer
...
|
But instead of reading user Input from Terminal it takes the next item from the program stack. How can I force to read user Input from terminal even that there are items in program stack?
Best regards

Optionally manipulate with stack levels:
| Code: |
"NEWSTACK" /* optional; program stack for input records */
"EXECIO * DISKR INPUTDD (FINIS"
Do iRec = 1 by 1 While Queued() > 0
[Parse] Pull NewRecord
If NeedToAskUser Then Do
"NEWSTACK" /* new program stack to isolate user's answer */
Say 'You need to keep this file?' filename
pull answer
"DELSTACK" /* return to previous stack level, to continue with data */
End
End iRec
"DELSTACK" /* optional; clean-up after reading file */
