Program Control with (i)
Since the contents of i can change each time a program runs–or even in
different parts of the same program — a program instruction such as
!6L5
can branch to a different label at different times. This maintains
flexibility by leaving open (until the program runs) exactly which variable or
program label will be needed. (See the first example below.)
Indirect addressing is very useful for counting and controlling loops. The
variable i serves as an index, holding the address of the variable that
contains the loop–control number for the functions DSE and ISG. (See the
second example below.)
Example:
Choosing Subroutines With (i).
The "Curve Fitting" program in chapter 16 uses indirect addressing to
determine which model to use to compute estimated values for x and y.
(Different subroutines compute x and y for the different models.) Notice that i
is stored and then indirectly addressed in widely separated parts of the
program.
The first four routines (S, L, E, P) of the program specify the curve–fitting model
that will be used and assign a number (1, 2, 3, 4) to each of these models.
This number is then stored during routine Z, the common entry point for all
models:
' ! L
Routine Y uses i to call the appropriate subroutine (by model) to calculate the
x– and y–estimates. Line Y03 calls the subroutine to compute y:
&
