returns		The number of characters in the C string, not including the NULL terminating
		character.

StrNCaseCmp

syntax int32 StrNCaseCmp(s1, s2, n);

StrNCaseCmp lexically compares two strings to determine whether one is less than, the same as, or greater than the other, limiting the comparison to n characters. StrNCaseCmp ignores differences in case in performing the comparison.

Parameter	Type	Description
s1	CStr	Pointer to a C string.
s2	CStr	Pointer to a C string.
n	uInt32	Maximum number of characters to compare.

returns	<0, 0, or >0 if s1 is less than, the same as, or greater than s2. Returns <0 if s1
	is an initial substring of s2.

StrNCmp

syntax int32 StrNCmp(s1, s2, n);

StrNCmp lexically compares two strings to determine whether one is less than, the same as, or greater than the other, limiting the comparison to n characters.

Parameter	Type	Description
s1	CStr	Pointer to a C string.
s2	CStr	Pointer to a C string.
n	uInt32	Maximum number of characters to compare.
