A Identifying Telephone Manager File Name Suffixes
Special files are identified to the system software on
the UNIX PC by appending a special suffix to the file
name. For example, the sample file example is
identified to the system as a sample file by the suffix
.hlp. Its full name is example.hlp.
Normally, you need not be concerned with these
suffixes. The suffix must be included with the
filename, however, if you refer to the file by typing
its pathname. If you list the contents of a folder
using the UNIX System V shell, you see the suffix
appended to the file name in this listing.
The length of the file name, including suffix, cannot
exceed 14 characters.
The following table lists the suffixes used with
objects included with the Telephone Manager software.
