Assembly Source Files

Assembly source files (
assembler directives, and (optionally) preprocessor commands. For infor-
mation on assembly instructions, see your processor's Programming
Reference.
The processor's instruction set is supplemented with assembly directives.
Preprocessor commands control macro processing and conditional assem-
bly or compilation.
For information on the assembler and preprocessor, see the
VisualDSP++ 3.5 Assembler and Preprocessor Manual.

Assembly Initialization Data Files

Assembly initialization data files (
floating-point data. These files provide initialization data for an assembler
directive or serve in other tool operations.
.VAR
When a directive uses a
.VAR
reads the data file and initializes the buffer in the output object file (
Data files have one data value per line and may have any number of lines.
The extension is explanatory or mnemonic. A directive to
.DAT
can take any file name and extension as an argument.
<file>
Fixed-point values (integers) in data files may be signed, and they may be
decimal-, hexadecimal-, octal-, or binary-base values. The assembler uses
the prefix conventions listed in
formats.
For all numeric bases, the assembler uses 16-bit words for data storage;
24-bit data is for the program code only. The largest word in the buffer
determines the size for all words in the buffer. If you have some 8-bit data
