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.

Press ŠZ to see that the loop–control number is now 11.0100.
