# StringReplaceAll

**StringReplaceAll** replaces all occurrences of **OldPattern** with **NewPattern** in **S** string.

**OldPattern** can be one or more characters.

**NewPattern** can be one or more characters, or it can be blank, which effectively removes all occurrences of **OldPattern**.

**StringReplaceAll** does not recognise case - **A** is read as the same as **a**.

Please also review **StringReplaceFirst** at [StringReplaceFirst](/statelake/scripting-reference/functions-and-procedures/string-functions/stringreplacefirst).

**Declaration**: Function StringReplaceAll( const S, OldPattern, NewPattern : string) : string;

Examples follow.

```pascal
procedure OnMapEvent(var Value:Variant);
var
  Str1, Str2, Str3, Str4 : string;
begin
  Str1 := 'T''was the night before Xmas, When all through the house.'

 //Returns 'abc|def|g'
  Str2 := StringReplaceAll('abc#def#g','#','|');
  LogInfo(Str2);

 //Returns 'T'was the night before Christmas, When all through the house.'
  Str3 := StringReplaceAll(Str1,'xmas','Christmas');
  LogInfo(Str3);

 //Returns 'abcdefg'
  Str4 := StringReplaceAll('abc#def#g','#','');
  LogInfo(Str4);

end;
```
