TEXT:00,Having a variable type as part of a variable declaration is a kind of
TEXT:16,safety system. It prevents a programmer from entering the wrong type
TEXT:16,of value into a variable. It also ensures that certain features of the
TEXT:16,Euphoria programming language that are meant to work on one data
TEXT:16,type do not get slipped with a variable value that is of a different
TEXT:16,data object type.
TEXT:32,Which brings us next to the topic of variable values. Is there
TEXT:16,an initial value placed inside a variable after it is declared? The
TEXT:16,answer is no. Don't get the impression, however, that there is nothing
TEXT:16,inside a variable. Most likely it is left-over data from a previous
TEXT:16,program run, and probably so garbled that it is unusable. For this
TEXT:16,reason, Euphoria rules dictate that a programmer must place a value
TEXT:16,inside a variable for the first time before it can be used.
