Typically, the filename extension is used to indicate the contents of each file. The following table lists the file name extensions that are used in the 251 tool chain.
| Extension | Content and Description |
|---|---|
| .A51 .ASM .SRC |
Source code file: contains ASCII text that is the input for the A251 assembler. |
| .C .C251 |
C source code file: contains ASCII text that is the input for the C251 ANSI C compiler. |
| .INC .H |
Include file: contains ASCII text that is merged into an source code file with the include directive. These files are input files for A251 or C251. |
| .OBJ | Relocatable object file: is the output of the A251 or C251 that contains the program code and control information. Several relocatable object files are typically input files for the L251 Linker/Locater. |
| .LST | Listing object file: is generated by A251 or C251 to document the translation process. A listing file typically contains the ASCII program text and diagnostic information about the source module. Appendix F describes the format of the A251 listing file. |

Absolute object file: is the output of the L251. Typically it is a complete program that can be executed on the 251 MCU. |
| .M51 .MAP |
