for

The for operator implements a counting loop. This operator takes three integers and one executable array:

   i0  d  i1  { ops } for

i0 is the loop counter's starting value, d is the increment amount, i1 is the final value. The for operator put the value of the counter on the stack before each execution of ops. For example, the program line

  1 1 5  { /i set i message } for

outputs

   1  2   3   4   5
