Given the loop–control number ccccccc.fffii, ISG increments ccccccc to ccccccc +
ii, compares the new ccccccc with fff, and makes program execution skip the next
program line if this
ccccccc
>
fff.

For example, the loop–control number 0.050 for ISG means: start counting at zero,
count up to 50, and increase the number by 1 each loop.
The following program uses ISG to loop 10 times. The loop counter
(0000001.01000) is stored in the variable Z. Leading and trailing zeros can be
left off.
