# AnsiCompareStr

Compare 2 ansistrings, case sensitive, ignoring accents characters.

## Declaration

Source position: sysstrh.inc line 84

`function AnsiCompareStr(`
`const S1: string;`
`const S2: string`
`):Integer;`

## Description

AnsiCompareStr compares two strings and returns the following result:

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

The comparision takes into account Ansi characters, i.e. it takes care of strange accented characters. Contrary to AnsiCompareText, the comparision is case sensitive.

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

## Errors
