Does Visual COBOL support the Net Express WINDOW1 preprocessor for ACU type popup windows for character applications? 

For example:

The following works in Net Express 5.1:

$set preprocess(window1)
 working-storage section.
 78 note-height value 16.
 78 note-width value 41.
 78 no-of-chars value note-height * note-width.
 01 note-window pic x(10).
 01 dummy pic x.
 01 note-data value all "- wallpaper ".
      03 note-char pic x occurs no-of-chars.
 screen section.
 01 input-data highlight.
      03 line 4 column 6 value " Accept and Display positions ".
      03 line 5 column 6 value " are relative to the top left ".
      03 line 6 column 6 value " corner of the window. ".
      03 pic x using dummy.
 01 note-screen pic x(no-of-chars) using note-data prompt " " reverse-video.
 procedure division.
* Put a blank window on the screen with a border and title
       display window, line 2, column 38, lines note-height,
             size note-width, boxed, erase, reverse
* Define a reference for this window so that it can be
* removed and the previous display restored 
       pop-up area is note-window
            bottom right title "Press Enter to remove window"
* Fill the window with the contents of note-screen
       display note-screen
       display input-data
       accept input-data
       close window note-window.

As of Visual COBOL 2.1 the support for the WINDOW1 preprocessor was added to Visual COBOL for native applications.

With Visual COBOL 2.1 we’ve reinstated the Windows1 pre-processor which has limited support for ACUCOBOL and RM/COBOL ACCEPT/DISPLAY functionality for popup windows in native code applications

The pre-processor does not currently support all functionality available with RM and ACU products but we will be enhancing this support to provide significant ACCEPT/DISPLAY coverage.

The example shown above will work under Visual COBOL.

If you are creating an .EXE or .DLL that uses WINDOW1 then you will have to also link to the library COBWIN2.obj by adding its name to the Project Properties page-->COBOL Link tab-->Link with objects field.
