Tips to writing out extended subfile records conditionally

Thanks for your input.  However the above will not work for me as each column has a different color and I need the individual fields to display the correct color.  The DDS manual references an "OVERLAY" option.  For the description, I gather that I can write a normal subfile out (While writing out I know that record 3 will have an subfile line, so I write an extra subfile line after record 3.  At the end, I write a record that "Overlays"  the subfile for this record.  Footers appear to be treated this way, but I cannot seem to get it to work.  Any examples would greatly be appriciated!!
Thanks!

Hi the colours are quite easy to do, they are simply hex codes are teh start of a field
20 Normal Green
21 Reverse image Green, reverse image
22 High intensity White
23 High intensity, reverse image White, reverse image
24 Underscore Green, underscore
25 Underscore, reverse image Green, underscore, reverse image
26 Underscore, high intensity White, underscore
27 Nondisplay Nondisplay
28 Blink Red
29 Blink, reverse image Red, reverse image
2A Blink, high intensity Red, high intensity
2B Blink, high intensity, reverse image Red, high intensity, reverse image
2C Blink, underscore Red, underscore
2D Blink, underscore, reverse image Red, underscore, reverse image
2E Blink, underscore, high intensity Red, underscore, blink
2F Nondisplay Nondisplay
30 Column separator Turquoise, column separator
31 Reverse image, column separator Turquoise, column separator, reverse image
32 High intensity, column separator Yellow, column separator
33 High intensity, reverse image, column separator White, reverse image, column separator
34 Underscore, column separator Turquoise, underscore, column separator
35 Underscore, reverse image, column separator Turquoise, underscore, reverse image, column parator
36 Underscore, high intensity, column separator Yellow, underscore, column separator
37 Nondisplay Nondisplay
38 Blink, column separator
39 Blink, reverse image, column separator Pink, reverse image
3ABlink, high intensity, column separator Blue
3B Blink, high intensity, reverse image, column separator Blue, reverse image
3C Blink, underscore, column separator Pink, underscore
3D Blink, underscore, reverse image, column separator
Pink, underscore, reverse image
3E Blink, underscore, high intensity, column separator Blue, underscore
3F Nondisplay Nondisplay

Wow!  I was not aware that this could be done.
The next problem is that some of the fields are input capable (Use can modify the data)
I have attached an example of the current screens/programs along with the "Future" screen.
The current screen does reuse some of the fields already.  I was hoping the "OVERLAY" option would work.  
I have tried the FOLD/UNFOLD which works ok, just the owner wants to see more data lines on the page.
If I cannot use the overlay option, I will modify the screen similar to what was done in the past (reuse predefined fields).
Thanks!!

Hi
It looks like the input fields occupy their own space on the sreen - if that is the case you can use indicators to:
a. Display the colour
b. Protect the field, if you use the ChgInpDft commnad to can remove the input underline so the screen looks like a continues output field.

Dave:
This is what I have done in the past.  Just protected the input fields, changed the color on the display fields and put the data for the extra lines into existing datafields.
I may go back to the above approach.

Thanks again!

I was thinking about other options; this is a bit more long winded bit gives you a massive amount of control.

Read the records into a multi occurance data structure, this would be the same process as populating your subfile.
Create x (x being the number of lines in the SFL F0401, f0402 etc..)  number of identical formats with the same field names, you need to code the RTNDTA keyword. and a different start line
Write  each of the formats dependtant on the ccurance of the MODS and what the record is.
The rtndta then allows you to read each of the formats as with the press of a single enter key


Example

   Write Header
   Write F0401 ;
   Write F0402 ;
   Write F0403 ;
...
   Write F0404 ;
   Exfmt  F0413 ;

   Read F0401 ;
   Exsr Validation ;

   Read F0402 ;
   Exsr Validation ;

....

Hi ChuckMason,

is it an option to make the screens extended with fold, so that initialy only 1 line is visible untill a Fkey is pressed?
or.... what about forgetting the subfile and makke 2 diferent 1 and 2 line screens with a variable startline?

Murph:
Thanks.  I have a version of the program running with the fold/drop function key.  The problem is that the customer does not want 2 lines to show for every record.  He only wants 2 lines to show when there is data to be displayed on the second line.  Typically there are 20 records to be displayed on the screen.  2 of these records would have extra information to be displayed.
I have taken Dave's approach above and defined several of my output only fields as one field.  Then conditionally output a extra subfile record in the same format. (Using an indicator to turn off the unneeded fields on the second subfile record.

According to the DDS manual, what I want to do is possible (using OVERLAY and PUTOVR in the DDS), I just can't get it to work :(
Thanks again!
