Precautions for Correct Use
Variable names have the following restrictions. The restrictions are applied to both variables:
Scene variables and System variables.
• The first character must be an alphabetic character.
• Alphanumeric characters, “.” (Period), and “_” (Underscore) can be used except for the first
character.
• Upper- and lowercase letters are not distinguished. When a lowercase letter is entered, it will
be converted to and displayed as an uppercase one automatically. Therefore, just use upper
or lowercase letters. e.g. “AA” and “aa” are treated as the same variable.
• Reserved words cannot be used as a variable name. A variable name including a reserved
word however can be used. e.g. Abs is one of the reserved words, so that it cannot be used
as a variable name. Abs_01 however can be used as a variable name.
For details, refer to List of Reserved Words on Macro Reference List in FH Series Macro
Customization Programming Manual (Cat. No. Z367).
