The following steps illustrate how to create an application
under the MS-DOS operating system:

1. Select PT500 as the current directory.
2. Type SETENV to set the environment.
3. Create a project file called APP.PRJ in the PT500

directory. It will contain one text line:
R03\APP.R03 R03\APPRES.R03. We will have
one C source file in sub-directory called
APP.C, and one Assembly source file in
sub-directory called APPRES.S03.

4. TYPE C51 APP.
5. TYPE ASM APPRES.
6. TYPE LNK APP.
7. Get APP.BIN. Download it to the portable and

run. Hold the scan key down. The portable will
scan again and again automatically every 3
seconds.
