Vbbinarycompare	0	Performs a binary comparison.
Vbdatabasecompare	2	Execution is based on a comparison of the information contained in the database (performing comparisons in this database).

string1 is zero length	0
string1 is Null	Null
string2 is zero length	Start
string2 is Null	Null
string2 didn't find it.	0
Find string2 in string1 .	Find the location of the matching string
start > Len (string2)	0

The following example uses the InStrRevFunction search string:

 dim searchstring, SearchChar, mypossearchstring = "Xxpxxpxxpxxp" to The string in which to search. SearchChar = "P" ' Search ' P '. The binary comparison starts with the 10th character. Returns 9. MyPos = instrrev ( searchstring SearchChar  10 0 ' text comparison begins with the last character. Returns 12. MyPos = instrrev ( searchstring SearchChar  -1 1)  ' defaults to binary comparison ( Last argument omitted). Returns 0. MyPos = instrrev ( searchstring SearchChar  8
