     Syntax: digits                     Integer, default radix
             fixed-point-number[#|!]    Single or double, fixed-point format,
                                        decimal radix
             floating-point-number[#|!] Single or double, floating-point
                                        format, decimal radix
             &Odigits                   Integer, octal radix
             &digits                    Integer, octal radix (alternate
                                        format)
             &Hdigits                   Integer, hexadecimal radix
 
     Constants can be entered in the Command, Watch, and Local windows as
     integer, long integers, single-precision, or double-precision data
     objects. Constants are evaluated according to the rules of the BASIC
     language. For information about the format and ranges of constants in
     BASIC, see BASIC Literal Constants.
 
     By default, CodeView displays numbers in decimal format. This format
     is referred to as the system radix. If you change the system radix to
     octal or hexadecimal, you cannot enter fixed-point or floating-point
     numbers. For information on how to change the system radix, see the
     CodeView Radix command.
 
     You can use the BASIC long-integer type identifier (&) to store an
     integer constant as a long (4-byte) integer, rather than as a short
     (2-byte) integer.
 
     If the system radix is set to hexadecimal, it is possible to enter a
     value or argument that could be interpreted either as a symbol or as
     a hexadecimal number. CodeView resolves this ambiguity by first
     searching for a symbol with that name. If no symbol is found, CodeView
     interprets the value as a number.
 
     To enter a value as a number when a symbol exists with the same name,
     use the hexadecimal format (&Hdigits). For example, to enter the
     hexadecimal number ABC when your program contains a symbol named ABC,
     enter it as &HABC.
