The list file reflects my code only. The MAP file says that only my test module is included. I mention that because Keil responded to my question with the following:

"Keil will always include a startup file in your project if you do not put a startup file in your project.

For example, if you look in the Map file (the file with the .51 extension, you will see these lines:

INPUT MODULES INCLUDED:
.
.
.
C:KEILC51LIBC51S.LIB (?C_STARTUP)
"

I am not sure Keil understands that I am not doing C development. I sent them another inquiry and was more specific.

I assembled the exact same code using our old assembler. The binary file is 15 bytes. The binary file assembled using the Keil assembler is 202 bytes. When I do a diff on the binary files, there is definitely alot of other code at the beginning of the Keil binary file. Even the Keil map file says that the program size is 15 bytes. Then, why is the binary file 202 bytes?

I am listing the map file for reference. Could someone please assemble the sample code I posted earlier(my second post, without debug info), and let me know how large your binary file is?
