A numeric literal is a string of digits that DEC DATATRIEVE
       interprets as a decimal number. A numeric literal may contain a
       decimal point and up to 31 digits. The decimal point is optional
       and is not counted in the maximum number of digits.

       A numeric literal can begin with a decimal point. Thus, for
       example, .5 is a valid numeric literal.

       A numeric literal cannot end with a decimal point. For example,
       123. is not a valid numeric, but 123.0 is.

       If you use a numeric literal to assign a value to a field or a
       variable, the data type of the field or variable controls the
       maximum value you can assign.
