WG: reading different files according to user input

ExtFile will work with externally described files, as long as they have the
same layout.

Here is just a simple solution for your problem
Select;
when Condition = 1;
     Chain(e) Key1 FileF1;
when Condition = 2;
     Chain(e) Key2 FileF2;
....
EndSL;

If %Found;
   DoW 1=0;
       exsr ForEachRecord;
       Select;
       when Condition = 1;
            reade(e) Key1 FileF1;
       when Condition = 2;
            reade(e) Key2 FileF2;
       ....
       EndSL;
       If %EOF;
          leave;
       EndIf;
   enddo;
EndIf;
