Hi Yusuf. I am running the same program. First exfmt , entered two records. Both are getting picked up and processed by the readc subr. On the next exfmt ,the screen is getting refreshed even though the clear indicator is off. Used OVERLAY keyword but still the entered values are getting cleared after second exfmt.

How to read records from non editable subfile..? I want to assign values from subfiles fields to printer file fields... the subfile is non editable...how do we do this

[@yusy4code]

In display file/sub file we have 4 different way of showing data. I, O, B, H. When u say non editable I guess you are referring Output 'O'. In all 4 cases, the variable names and its data is visible inside program. Only on the UI, the fields are either Input, Output, Both or Hidden. So you can assign the value of the DSPF field into your PRTF field.

Hi Yusuf.. My query is.. What if the program doesn't end with process SR and it continues as a loop to validate SR again.. I may have to use the SFLNEXTCHG indicator in the Process SR too right? If the answer is yes means.. Can u tell me where in particular and how to use the same .. Thanks in advance..

[@yusy4code]

Hi Kavin, the process routine expects that data is already validated in validate SR. So once the data is validated in validate SR, then process SR will just read all the data using READC and process it. May be if you want user to enter more data after process SR, then you will display the screen again and validate using validate SR and process using process SR. So Exfmt , Validate & Process should be in single loop.
