(*1) Characters that cannot be used in data names
 Reserved characters (AUX, CON, PRN, NUL, COM1 to COM9, LPT1 to LPT9, and CLOCK$)
 Data names that include these characters result in error: ", =, |, :, ;, ,, \, [, ], +, *, ?, <, >, . and /
The following characters also cannot be used.
 Special NEC selected IBM extended characters (character codes: 0xED40 to 0xEEEC)
 IBM extended characters (character codes: 0xFA40 to 0xFC4B)
 Characters of character codes that have the same appearance as NEC selected IBM extended characters and IBM
extended characters within the range of character codes 0x849F to 0x879C
Example: Roman numerals (I to X), ≒ , ≡ , ∫ , ∮ , Σ, √ , ⊥ , ∠ , ⊿ , ∵ , ∩ , ∪ , № , ℡ , and ㈱ .
If any of these characters are used, processing that uses PLC data (opens, saves, etc.) will not execute correctly.
