Pathname

The name of the directory combined with the names of one or more subdirectories is called a pathname. Volume names and subdirectory names are preceded by a slash, “/”. (Note that some applications add the slash for you.) For example, you could have a volume named /MY.DISK and have a file, called /MY.FILE on the root directory of that disk. To access that file, you would use the pathname /MY.DISK/MY.FILE. You could also have a file, /JUL.AUG in a subdirectory (folder) called, /PHONE on a disk called /BILLS. To access that file, you would use the

pathname, /BILLS/PHONE/JUL.DEC. Refer to the

diagram below.

ProDOS Directory Structure

Now when an application asks you for the pathname of a file, you'll have a basic understanding of what it expects.

System Files

A system file is a ProDOS file that starts an application. Typically, these files have the suffix, . SYSTEM (e.g.

/APLWORKS . SYSTEM, /ACCOUNT . SYSTEM [see above], etc.).

When you boot ProDOS, it runs the first system file listed in its directory. So, if BASIC.SYSTEM is the first system file on your ProDOS boot disk, ProDOS will boot then put you in BASIC.
