4.1.10 Local Labels
4.1.11 Default_Symbol_Tables
Here are some examples of valid symbols:
The following code demonstrates how to use the local label :loop for common
looping purposes within two globally-labeled routines.
and must contain only letters, numbers, underscores, and colons. Further, if you’re
labeling an address (such as the start of a routine), the label must start at the beginning
of the line.
By default, labels are global, which means that they can be "seen" from anywhere in your
program. Sometimes, however, you may want to use a local label, which can only be
"seen" within a limited part of your program (the area in which the local labe l can be
seen starts at the preceding global label, and continues up to the following global label).
Local labels have the same syntax rules as global labels, except they must begin with a
colon (:), and must be referenced with a colon. Local labels can be referenced from
outside their normal area by referring to preceding global label name:local label name.
A Local label can be called from outside its usual area as demonstrated in the line:
When the assembler is started, its symbol table is initialized with various PIC symbols,
such as C for the Carry register, RA for Port A, etc. This saves you from having to define
