User Manual
Error and warning messages follow the source line containing the error(s). A count of the
errors and warnings detected is included at the end of the listing output file.
The addresses in the assembly listing are relative. To convert the relative addresses into
absolute addresses, select the
Show Absolute Addresses in Assembly Listings check-
box on the Output page of the Project Settings dialog box. This option uses the informa-
tion in the .src file (generated by the compiler when the Generate Assembly Source
Code checkbox is selected [see Project Settings—Listing Files Page – see page 53]) and
the .map file to change all of the relative addresses in the assembly listing into absolute
addresses.
Object Code (.obj) File
The object code output file name is the same as the source file name with an .obj exten-
sion. This file contains the relocatable object code in OMF695 format and is ready to be
processed by the linker and librarian.
Source Language Structure
This section describes the form of an assembly source file.
General Structure
A line in an assembly source file is either a source line or a comment line. The assembler
ignores blank lines. Each line of input consists of ASCII characters terminated by a car-
riage return. An input line cannot exceed 512 characters.
A backslash (\) at the end of a line is a line continuation. The following line is concate-
nated onto the end of the line with the backslash, as exemplified in the C programming
language. If you place a space or any other character after the backslash, the following line
is not treated as a continuation.
Source Line
A source line is composed of an optional label followed by an instruction or a directive. It
is possible for a source line to contain only a label field.
