Just letters, figures and underscore may be used for the variable name. A letter or an underscore should be the first letter of a variable. No variable length policy exists.

The name of the variable indicates what the variable contains details. The defined information will shift but the functions of the variable must stay the same.

They are called variables. In general, the "Symbolic" notation should be written to make a statement always symbolically valid.
