Referring to documentation rev. 655.
p. 55, ITERATE keyword instruction.
It would be helpful, if there was also an example for a label name to be used
for ITERATE, like:
loop label myLabelName i=1 to 4 /* label set to "MYLABELNAME" */ if i=2 then iterate myLabelName say i end myLabelName /* Displays: 1 3 4 */
