Programming Techniques
Chapter 12 covered the basics of programming. This chapter explores more
sophisticated but useful techniques:

Using subroutines to simplify programs by separating and labeling
portions of the program that are dedicated to particular tasks. The use of
subroutines also shortens a program that must perform a series of steps
more than once.

Using conditional instructions (comparisons and flags) to determine
which instructions or subroutines should be used,

Using loops with counters to execute a set of instructions a certain
number of times.

Using indirect addressing to access different variables using the same
program instruction.
Routines in Programs
A program is composed of one or more routines. A routine is a functional unit
that accomplishes something specific, Complicated programs need routines
to group and separate tasks. This makes a program easier to write, read,
understand, and alter.
For example, look at the program for "Normal and Inverse–Normal
Distributions" in chapter 16. Routine S "initializes" the program by collecting
the input for the mean and standard deviation. Routine D sets a limit of
integration, executes routine Q, and displays the result, Routine Q integrates
the function defined in routine F and finishes the probability calculation of
Q(x).
