The File application uses the. FlL extension for files containing File layout
information (column widths, name, and so forth) and the .DAT extension
for data files. The. TXT extension is used by Telcom for the capture to
file (SESSION. TXT). Telcom script files use a .TEL extension. Refer to
the "File" and "Telcom" chapters for more information.
You do not enter a file extension for an application file when you run it; the
computer opens the appropriate file according to the application line on
which it appears. The Copy, Delete, List, and Name commands, however,
do require a filename extension.
Unspecified Data Files
The Tandy 600 can store two types of data files: work files, created in
applications, and "unspecified" data files. Unspecified data files are those
that do not contain filename extensions or that use file extensions not
recognized by the Tandy 600 applications. This happens when a file is
copied or renamed without adding the appropriate extension. Files copied
into memory from an external source, such as CompuServe or the Dow
Jones News/Retrieval Service are also unspecified data files.
A list of unspecified data files appears on the liners) after the last
application. A period or the extension appears to the left of the double
lines to indicate unspecified data files.
Using Unspecified Data Files in Applications
If the data in an unspecified file comes from a Tandy 600 application or a
compatible microcomputer application, you need only rename it, using the
appropriate extension, to access it from the application.
