Here is a c++ string class:

Class String {

// two data mbrs. lgth of the string and
// a ptr to string data.
  int mnLgth ;
  char* mpData ;

// an assignment member function.
// user of the class codes as: string1 = string2
// ( some confusing symbols left out )
String operator=( const String string2 ) ;
} ;

// here is the assignment mbr function code.
String String::operator=( const string2 )
if ( mpData != NULL )
  free( mpData ) ;  // free old string

// allocate string memory.
  mnLgth = string2.GetLgth( ) ;
  mpData = malloc( mnLgth + 1 ) ;

// store the string value.
  strcpy( mpData, string2.GetBuffer( ) ) ;

  return *this ;

The string class is then used in a pgm:
  String sEvilDoer ;
  sEvilDoer = "Ibm leadership" ;

This code takes a lot of cpu to run, is bloat free, abstracts away a bunch of 
details the pgmr does not need to have deal with, does not give much chance to 
optimize and would make our as400 grind to a halt if run as frequently as 
efficient RPG pgms are run.
