Interpret strcmp (String_Type a, String_Type b)
The strcmp function may be used to perform a case-sensitive
string comparison, in the lexicongraphic sense, on strings a and
b. It returns 0 if the strings are identical, a negative integer
if a is less than b, or a positive integer if a is greater
than b.
The strup function may be used to perform a case-insensitive
string comparison:
define case_insensitive_strcmp (a, b)
{
return strcmp (strup(a), strup(b));
}
One may also use one of the binary comparison operators, e.g.,
a > b.
