Appendix 1.2 System Name
A system name is used to group and organize programs or data in a memory card, FD
or HD.
Any name can be used for a system name as long as it conforms to the following
conventions.
Characters that can be used
Alphabet (A to Z, a to z)
Numbers (0 to 9)
Kana (@@@@@)
Kanji (JIS level 1 standard Kanji and non-Kanji)
Certain symbols (!, #, $, %, &, ‘, (,), -, @, ^, _, {, }, ~)
Number of characters that can be used
8 characters or less. Note that each Kanji character is counted as two characters.
System names that cannot be used
The following words have special meanings and therefore cannot be used.
AUX, CLOCK, CON, NUL, PRN, BAT, COM, EXE
However, these words can be used as a part of a system name.
Example
AUX X
AUXNO
TOAUX
TOAUXNO
note
• When specifying only a drive number and system name in an instruction such as
the FILES instruction, always place a \ character (
\
if there is no ¥ character on the
keyboard) after the system name.
• A system name must be unique within the same memory card, FD, or HD.
REMARK
System names in AD51H-BASIC are equivalent to sub-directories used in MS-DOS.
However, unlike a sub-directory in MS-DOS, a system name cannot be created
under another system name.
