This routine (taken from the "Coordinate Transformations" program on page
15–32 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
t
N for the old–to–new system or
t
O 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.
