Changes
add max variable length information
== Variables ==
Many contemporary BASIC interpreters only supported the first few characters of a variable name as a discriminator. For example <code>WATER$</code> and <code>WALDO$</code> would refer to the same variable on a Commodore 64 or Apple II. But Locomotive BASIC allowed variable names up to 40 characters in length, so <code>THEQUICKBROWNFOXJUMPEDOVERTHELAZYDOGFAST$</code> and <code>THEQUICKBROWNFOXJUMPEDOVERTHELAZYDOGFATS$</code> could be use as separate variables.
