+"STRNCMP" is a function words that compares up to n characters of
+character sequences s1 and s2, and returns the difference of the first
+differing characters, as in +s2[i] - s1[i]+, or 0 if all n characters
+are the same.
+I.e., the value v is less than 0 if string [n:s1] is alpha-numerically
+less than [n:s2],
+v is greater than 0 if [n:s1] is greater than [n:s2],
+and v is 0 if [n:s1] and [n:s2] are equal.
