4.1.12 Comments
4.1.13 Assembler Directives

Comments can be placed anywhere in your source code, beginning at any point on a line and
continuing to the end.
Assembler directives are instructions that direct the assembler to do something.
PicTools Manual 3.0
every register and bit in the PIC.
As the number of different PICs has grown, it has become necessary to have separate
symbol tables for each PIC. At the beginning of your program, you must tell the
assembler which PIC is being used. This is done with the INCLUDE directive (explained
later in this chapter).
If you’d like to see the symbol table for a particular PIC, please refer to the device include
files installed with the assembler (default location = C:\PicTools\*.inc). These files are
named according to the targeted device.
A semicolon initiates a comment. The following are example comments:
Blank lines can be used to provide space between lines and make the code more
readable.
Directives do many things; some tell the assembler to set aside space for variables,
others tell the assembler to include additional source files, and others establish the start
address for your program. T he directives available are shown below:
ORG
or register address during assembly. For example, ORG 0100h tells the assembler to
assemble all subsequent code starting at address 0100h.
