Use CALL SCREEN 200 (second one - display data) in the PAI of SCREEN 100 (first one - input customer) when leaving 200 in PAI (BACK) use LEAVE TO SCREEN 0.

HI,

use SET SCREEN 'SCRNO' OR CALL SCREEN 'SCRNO'.

set screen: used when we want to go to next screen after executing current screen.

call screen: navigates to the next screen executes it and comes back to current screen and process it before it had left. and also call screen is used for calling sub screens also.

Leave screen: used to go out of current screen.

in ur case.

in PAI event of 1st screen

write like this

CALL SCREEN '200' // 200 IS NEXT SCREEN

SET SCREEN '200'.

if helpful reward some points.

with regards,

Suresh Aluri.
