CompareText

unit
Sysutils
category
string handling routines

declaration
function CompareText(const S1, S2: string): integer;

description
Compares two strings without case sensitivity.

The comparison is NOT case sensitive and does not consider the Windows locale settings. The return integer value is less than 0 if S1 is less than S2, 0 if S1 equals S2, or greater than 0 if S1 is greater than S2.

This function is obsolete, i.e. it should not be used in new code - exists only for backward compatibility.

example
var s1,s2 : string;
        i : integer;

s1:='Delphi';
s2:='Programming';
i:= CompareText(s1,s2);
//i<0 because D is less than P in ascii order.
