Constants
A constant is a fixed quantity. Constants may be integers, floating point
values, or character string constants.
Integer Constants.
An integer constant may be defined as a sequence of numeric characters
optionally preceded by a plus or minus sign. If unsigned, the debugger
assumes the value is positive.
Positive integer constants may range between 0 and 2**31-1. When a constant
is negative, its two's complement representation is generated. Negative
integer constants may range to –2**31.
Constants can be specified as binary, decimal, or hexadecimal values. This is
done by placing a prefix or suffix descriptor before or after the constant. The
