Restrictions on file names in the list file
The following restrictions apply when file names are specified in the
list file.
<1> Only the following 76 different ASCII characters can be used in
arbitrary file names.
Digits 0 to 9
Lowercase letters a to z
Uppercase letters A to Z
14 different special characters . (period), ! , #, $, %, &, -, @, ^, _,
', {, }, and ~
This restriction applies also when the name of a file held on the
host computer built-in hard disk is specified.
<2> The arbitrary file name can be up to 255 characters. If an attempt
is made to specify a larger arbitrary file name, an error is detected.
<3> Any file to be used on the data server board built-in hard disk must
be in the 8.3 format. If an "arbitrary" file name is not in the 8.3
format, it is converted to an 8.3-format file name automatically
according to the following rule:
- If the first 8 characters in the original "arbitrary" file name
include no period, they are used as the post-conversion file
name. If they include a period, the characters before the
period are used as the post-conversion file name. If the first
3 characters after the period include no period, they are used
as the post-conversion file extension. If they contain periods,
a characters between the first and second periods are used as
the post-conversion file name extension.
Example 1) If the original file name is
"LONGFILENAME.LONGEXT," the post-
conversion file name is: "LONGFILE.LON"
Example 2) If the original file name is
"ABCD.EFGH.TXT," the post-conversion file
name is: "ABCD.EFG"
NOTE
The names of files handled in the data server must be
in the 8.3 format. If "arbitrary" file names are not in
the 8.3 format, they are converted to this format
automatically when they are handled in the data
server. Different "arbitrary" file names may be
converted to the same file name in the 8.3 format;
therefore, they will be regarded as the same file.
