That is an excellent paper! I rarely use goto, but sometimes it is the best solution to a problem. (Example: escaping from multiple nested loops.) I once read someone’s general rule that you always go forward, but I found one exception years ago:
NEXT_BYTE:
if( x>xmin ) {
Byte = *(--vptr);
/* Skip whole bytes */
if( Byte == 0xFF ) {
x -= 8;
goto NEXT_BYTE;
}
}
Sure the above code could be written using a loop and originally was, but this increased the speed (graphics code) enough to justify its use at the time.
