A constant retains its value, by definition. Variables may be changed in the course of a program. A variable may take on any value that is allowable for either a a

string or numeric constant.

Unlike some other programming languages $($e$.$g$.$ FORTRAN$),$ the type of variable is not determined by the name or any kind of declaration.

Variable names are in the format of $1$ alphabetic character, followed by any number of other MIIS legal characters.

Here are some examples of acceptable variable names:

ABC

If a variable is set equal to a string value, such as $"$##$$",$ it will be a string variable. The very same variable may be converted to a numeric variable by setting

it to a numeric constant.

A$0$

and $3($above$)$
