Create a table with function names and the actual function, for example:

type  Tsetupfunc_mapping=record
        name:string;
        func:setupfunc;
      end;
  
const setupfunc_mapping:array[0..2] of Tsetupfunc_mapping=(
       (name:'setup_function_1';func:@setup_function_1),
       (name:'setup_function_2';func:@setup_function_2),
       (name:'setup_function_3';func:@setup_function_3));

Then search the name of the function you want to call in the table, then 
call the function in the "func" field.
