a com file is a type of simple executable file. on the digital equipment operating systems of the 1970s, codice_1 was used as a filename extension for text files containing commands to be issued to the operating system (similar to a batch file). with the introduction of cp/m (a microcomputer operating system), the type of files commonly associated with com extension changed to that of executable files. this convention was later carried over to dos. even when complemented by the more general exe file format for executables, the compact com files remained viable and frequently used under dos.

bullet::::- jerusalem-1663: this virus infects .exe and .com files, including command.com. once memory resident, it infects programs as they are run. it causes .com and .exe files to grow by 1,663 bytes, but it cannot recognize infected files, so it may re-infect both .com and .exe files.
