Copy Source File
.copy, .include
6-17 Assembler Directives
Syntax .copy “
filename”
.include “
filename”
Description The .copy and .include directives tell the assembler to read source state-
ments from a different file. The assembler:
1) Stops assembling statements in the current source file
2) Assembles the statements in the copied/included file
3) Resumes assembling statements in the main source file, starting with the
statement that follows the .copy or .include directive
The filename is a required parameter that names a source file. The filename
must be enclosed in double quotes and must follow operating system conven-
tions. You can specify a full pathname (for example, c:\dsktools\file1.asm). If
you do not specify a full pathname, the assembler searches for the file in the
current directory.
The .copy and .include directives can be nested within a file that is copied or
included. the assembler limits this type of nesting to eight levels; the host oper-
ating system may set additional restrictions.
Example This example shows how the .include directive is used to tell the assembler
to read and assemble source statements from other files, then to resume as-
sembling into the current file.
Source file: (source .asm)
; Filename: source.asm
.space 10h ; Filename: source.asm

First copy file: (byte.asm)
; Filename: byte.asm
.byte ’a’, 0ah, 32 ; Filename: byte.asm
.include “word.asm” ; Filename: byte.asm
