Seems to be some confusion between calculator models here! On the TI-83
names of lists are (usually) required to be prefixed with a special character
(a tiny L) to distinguish them from the names of regular numeric variables.
Thus you can have both A and LA as names of variables (where that is
not a capital L but a tiny one, as described). The user is limited to
27 single-letter names for numeric (scalar) variables, but list names
preceded with the special L character can be several characters long,
so that you could have both LX1 and LX2 for example. As a convenience
to the user in entering names of lists, the special L character is built
in as one of the choices on the LIST menu.
On the TI-86, of course, names of _any_ variables are allowed to be more
than one character in length, and no special type-symbol prefixing any
name is required. The variable x could refer to a scalar or to a list
(though it's probably good practice to _choose_ easily recognizable names
for lists -- one of the fine points of programming style). Actually,
names in the TI-86 environment are case-sensitive, so that the variable
X could be used for a different purpose. Good programming practice, again,
would suggest not mixing together use of x and X, though.
Anyway, hope this clears things up.
