IF Y1 = 'Y' THEN
DO
CALL READCAT
...
Where is the value of Y1 set to 'Y'? Is that what the panel does? |

use TRACE('r')
Move the trace higher in the program. Show us the trace.
Remove the QUEUE and PULL instructions... they do not seem to do anything.
You are not passing any arguments to READCAT, but it seems to expect one. And READCAT is returning a value, but the caller does not expect a response. I suggest invoking it as a function:
| Code: |
| result = READCAT(y1) |
(sorry, the usage of Y1 or end_of_data is not clear to me, not sure what the argument is supposed to be) |
