2-4 ROM-DOS 6.22 User Manual 7/9/98
Some application programs, such as word processors, may use or
require particular file extensions for output or input files. It is best to
follow the application instructions regarding proper file name
extensions for that particular program.
Examples
A file could be named simply:
LETTER1
The same file name could have an extension included:
LETTER1.DOC
or
LETTER.XYZ
An executable program might have the file name:
RUNME.EXE
It is possible to have several files with the same file name but different
extensions. ROM-DOS searches for and accesses the file extensions
in order of .COM first, .EXE second, and .BAT third, then all others.
For example, you could have an executable file called MYPROG.EXE
and a batch file call MYPROG.BAT. If you typed MYPROG at the
command line, the file MYPROG.EXE would be executed. If you
wanted to execute the batch file MYPROG.BAT, you would have to
specify the .BAT extension on the command line.
