I have the following text file that I want to modify using Perl (this is just a text file I am reading in): ------------------------------------------------------ 
select (name)
{                        //want to delete this { brace
   case(a=b):
    {                    // delete this { brace
     if (d=e)
       {                 // keep this { brace for if loop
        call pgmA;
        return rc;
       }                // keep this } brace for if loop
    }                   // delete this } brace
   default:
     {                  // delete this { brace
     call pgmB;
     }                  // delete this } brace
}                       // change the last } brace to END;

I want to delete some of the left curly braces (but not all) and change the last closing brace } to an "END;" so that the modified text looks like: 
select (name)
                          
   case(a=b):
                          
     if (d=e)
       {                  ----->keep this opening brace in
        call pgmA;               if loop
        return rc;
       }                  ----->keep this closing brace
                        
   default:
     
     call pgmB;
     
END;                      ----->change last } to END;

Can anyone suggest a solution? I know how to search for patterns, but I cannot figure out how to change the occurrence of some characters but not to change other occurrences of it. Thanks for your time, Susan
