In Native COBOL you can have something like this:

       01 MyData.
           05 MyString1        Object Reference.
           05 MyString2        Object Reference.
           05 MyString3        Object Reference.
           05 MyString4        Object Reference.
           *> This is just a simplist list, there could be 100's
       01 ProgramToCall        PIC X(6).
       procedure division.

          *> Program Names are build dynamically and called in a variable.
          move "ABCDEF" to ProgramToCall
          Call ProgramToCall using MyData

Now moving to COBOL .NET this has to change as Object References must be on an 01 Level.

All of my programs are in separate projects.

All program Names  are called inside a variable

All Linkages to different programs change depending on the program being called, some might not have any Object References, others my have 100's

Q1. How do I simulate the same process in COBOL .NET?
Q2. Can I do it without creating a project references? (Make it more dynamic)
Ideas?

One option is to make MyData a valuetype, for example:

Close...but still not right - What did I do wrong?

Created a Solution.
Created ProgramA project 

Created ProgramB Project which compiles to ProgramA's folder.

       valuetype-id MyValueType.
       working-storage section.
       01 MyString1 string public.
       01 MyString2 string public.
       01 MyString3 string public.
       01 MyString4 string public.
       end valuetype.

       identification division.
       program-id. ProgramA.
       01 MyData type MyValueType.
       01 ProgramToCall PIC X(256).
       procedure division.
           set MyData::MyString1 = "Hello"
           set MyData::MyString2 = "World"
           set MyData::MyString3 = "From"
           set MyData::MyString4 = "COBOL"
           *> Program Names are build dynamically and called in a variable
           move "ProgramB" to ProgramToCall
           Call ProgramToCall using by value MyData
               on Exception
               display "Failed"
           stop run.
       end program ProgramA.

       valuetype-id MyValueType.
       working-storage section.
       01 MyString1 string public.
       01 MyString2 string public.
       01 MyString3 string public.
       01 MyString4 string public.
       end valuetype.

       identification division.
       program-id. ProgramB.
       procedure division using by value MyData as type MyValueType.
           display MyData::MyString1
           display MyData::MyString2
           display MyData::MyString3
           display MyData::MyString4
           goback.

       end program ProgramB.

System.InvalidCastException: '[A]MyValueType cannot be cast to [B]MyValueType. Type A originates from 'ProgramA, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\\TestProgramLinks\\ProgramA\\bin\\Debug\\net8.0\\ProgramA.dll'. Type B originates from 'ProgramB, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\\TestProgramLinks\\ProgramA\\bin\\Debug\\net8.0\\ProgramB.dll'.'
