Expressions
Mathematical expressions are used in many instructions. These expressions may be created using the
following operators:
Some example expressions:

Symbols are used to name locations and values within your program.
affect the result of expressions. For instance, the expression 5+2*4 would normally be resolved as

Many people refer to address symbols as "labels", but both have the same effect. For
instance, by assigning a symbol to the start of an important routine, you can later call that
routine by its name, rather than its address. And by giving a symbol to a common value,
you can refer to it by its name. Rather than typing "212" many times in your program, you
can type HOT = 212 at the beginning of your program, and then use HOT wherever you
need it. This is also quite handy if your idea of what’s "hot" changes. By changing the
symbol definition, you can easily redefine HOT to be a different temperature.
Symbols may be up to 32 character long. They must begin with a letter or underscore (_)
however, the example would be resolved as (5+2)*4, for a result of 28.
