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.
