Variable names can be composed of letters, dollar signs, underscores, and number signs.

No other characters can be used.

A variable name must start with a letter, after which any combination of the allowed characters can be used.

The maximum length for a variable name is 30 characters.

Variable names, like those of keywords and other identifiers, are not case sensitive.
