How To Format File Names - Tandy 1200 HD User Manual

You can use a file name as often as you wish, so long as it is used
only once on any given disk. (See the Disk Operating System manual
for an explanation of how hierarchical directories can be used to get
around this.
)
There are other matters that can be taken into consideration when
you assign base names and extensions. You may want to refer to the
Disk Operating System manual for more information on the subject.
Appendix E of this manual provides an introduction to the use of
global characters in file names.
HOW TO FORMAT FILE NAMES
Here are a few rules and guidelines that summarize what you have
learned about the naming of files.
a.
The base name is not optional. It must be from one to
eight characters in length, without any spaces between
characters.
b. The extension is sometimes optional. If it is used, a
period must separate it from the base name. If it is not
used, no period should follow the base name.
c. An extension, if used, must be from one to three
characters in length.
d. The period can be used in only one place: between the
base name and its extension.
e. The colon can be used in only one place: between the
drive specifier and the base name.
f. The drive specifier is optional if the file is to be stored on
the default drive.
g.
None of the following characters may be used anywhere
in the name of a file:
0
the blank character (the space created by pressing the
spacebar)
2 - 30
