Declaration

Source position: sysstrh.inc line 93

function AnsiCompareText(

const S1: string;

const S2: string

):Integer ;

Description

AnsiCompareText compares two strings and returns the following result:

<0: if S1<S2.
0: if S1=S2.
>0: if S1>S2.

the comparison takes into account Ansi characters, i.e. it takes care of strange accented characters. Contrary to AnsiCompareStr, the comparison is case insensitive.

Remark: A widestring manager must be installed in order for this function to work correctly with various character sets.

Errors

None.
