Variable Naming Requirements

Variable Naming Requirements apply to both String and Numeric variables.

  • May contain any letter, number or underscore.
  • Must begin with a letter or an underscore.
  • May not contain dashes, spaces or any characters other than letters and underscores. In other words, characters such as - , ; : * ! @ # $ % ^ & ( ) + and many others are not allowed in a variable name.
  • May not exceed 30 characters.
  • May not start with "fn" as that prefix is reserved for User Defined Functions.
  • BR variable names are case-insensitive, so myVariable$ and Myvariable$ will refer to the exact same variable.
  • String variable names must end with a $.
