NAMES
A file name consists of a prefix, an
optional separator (the period "."), and an
optional extension. A prefix is at most eight
characters in length, an extension is at most
three. Both prefixes and extensions may consist
of any character except the period and the null
(control @). Implanting obscure characters in
either can form a crude sort of file security
(at least they are hard to enter on the
keyboard) but good practice is to restrict the
character set to letters, digits, the underscore
("_") and the dash ("-").
Extensions are used to distinguish,
somewhat arbitrarily, between types of files.
EXE and COM files are presumed to be executable.
The meaning of most others is established by
convention. The period without an extension is
equivalent to a blank extension.
A path name consists of a file name
preceded by directory names separated by the
back slash ("\"). LOCATE returns as many of the
directory names as necessary to locate the file
from the directory from which INDEX was run.
LOCATE does not use volume names.
