9.5 Preprocessor Pseudo-Instructions
The principal mission of the pp33 is to expand the preprocessor pseudo-instructions, explained below, to
mnemonics that can be processed by the Assembler as33.
For clear discrimination from the assembler pseudo instructions, the preprocessor pseudo-instructions all begin
with a sharp (#). Describe the instructions always from top of the lines.
The pseudo-instructions in themselves are all in lowercase characters only. Parameters can use both uppercase
and lowercase characters, which are discriminated, respectively.
The lines of preprocessor pseudo-instructions also follow the notation rules of statements (see Chapter 4).
9.5.1 Include Instruction (#include)
The include instruction inserts the contents of a file in any location of a source file. It results useful when the
same source is shared in common among several source files.

#include "<file name>"
Sample descriptions:
The specified file is inserted in the location where #include was described.
For sample expansions, refer to Section 9.11 "Sample Executions".
A drive name or path name can as well be specified as the <file name>.
One or more spaces are necessary between the instruction and the "<file name>".
Only files created in text file format can be inserted.
Nesting is limited to maximum 2 levels. If this limit is surpassed, an error will result.
When adding a relative path to the file name, specify the relative path from the directory in which the
current source file exists.

#include "file2.s"
"file3.s" can be included in "file2.s", but "file4.s" cannot be included in "file3.s".
