Syntax of InStr

InStr([start,]string1,string2[,compare])

The InStr function can return the following values:
* If string1 is "" - InStr returns 0
* If string1 is Null - InStr returns Null
* If string2 is "" - InStr returns start
* If string2 is Null - InStr returns Null
* If string2 is not found - InStr returns 0
* If string2 is found within string1 - InStr returns the position at which match is found

Syntax of strcmp
strcmp ( const char * str1, const char * str2 )

Strcmp can return the following values:
*A zero value indicates that both strings are equal.
*A value greater than zero indicates that the first character that does not match has a greater value in str1 than in str2;
*And a value less than zero indicates the opposite.
