12.5.3.2 Loops and Repetitions within the current Command List

Loops are used to repeat all or part of a sequence of commands within the current list.

The repeated commands may, of course, include calls to sub-routines

• Repeating a path exactly N times.

  Roughly equivalent to:

  Copy

  for (var i = N; i > 0; --i) {    // LOOP_START N
  
  stuff();
  
  }    // LOOP_END
  
  // etc

• Repeating a path up to a maximum of N times.

  Roughly equivalent to:

  Copy

  for (var i = N; i > 0; --i) {    // LOOP_START N
  
  if (IOPort.Read() == CONDITION) goto lineNumStuff; // BRANCH_ABS_COND
  
  goto lineNumAfterEndOfLoop;            // LOOP_BREAK
  
  lineNumStuff:
  stuff();
  
  }    // LOOP_END
  
  lineNumAfterEndOfLoop:
  
  // etc
