I replies would use reflection. So I dropped my friend a mega simple demo… and here it is.

       $set ilusing"System.Reflection"

        01 myAssembly type "Assembly".
        01 usedAssemblyName type "AssemblyName".

        set myAssembly to type "Assembly"::"GetExecutingAssembly"

        display "My exe is " myAssembly::"FullName"
        display "and is using CLR " myAssembly::"ImageRuntimeVersion"
        display "and is loaded from " myAssembly::"Location"
        display "the initial method of this program was "
          myAssembly::"EntryPoint"::"Name"

        display "This assembly references -> "
        perform varying usedAssemblyName
             through myAssembly::"GetReferencedAssemblies"
              display "-> " usedAssemblyName
        end-perform

And the output of the program is:

My exe is clrver, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
and is using CLR v2.0.50727
and is loaded from d:\clrver.exe
the initial method of this program was _MF_ENTRYThis assembly references ->
-> mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
-> MicroFocus.COBOL.Runtime, Version=3.6.0.0, Culture=neutral,
PublicKeyToken=0412c5e0b2aaa8f0
