Loops

Branching backwards — that is, to a label in a previous line — makes it possible to execute part of a program more than once. This is called looping.

    "!   "!   "! !  ! 

This routine (taken from the "Coordinate Transformations" program on page 15–31 in chapter 15) is an example of an infinite loop. It is used to collect the initial data prior to the coordinate transformation. After entering the three values, it is up to the user to manually interrupt this loop by selecting the transformation to be performed (pressing WN for the old–to–new system or WO for the new–to–old system).

Conditional Loops (GTO)

When you want to perform an operation until a certain condition is met, but you don't know how many times the loop needs to repeat itself, you can create a loop with a conditional test and a GTO instruction.

For example, the following routine uses a loop to diminish a value A by a constant amount B until the resulting A is less than or equal to B.
