ObjectPascal SetString Procedure Copies characters from a buffer into a string System unit

procedure SetString ( var TargetString : string; BufferPointer : PChar; Length : Integer ) ;

Description The SetString procedure sets the length of TargetString to Length before copying that number of characters from the buffer referenced by BufferPointer.   The length is only set when the string is not a ShortString. In fact, the string is reallocated - the TargetString reference is then set to point to this new string. Related commands FillChar Fills out a section of storage with a fill character or byte value SetLength Changes the size of a string, or the size(s) of an array StringOfChar Creates a string with one character repeated many times		Example code : A simple example var   target : string;   source : array[1..5] of Char;   srcPtr : PChar;   i      : Integer; begin   // Fill out the character array   for i := 1 to 5 do     source[i] := Chr(i+64);   // Copy these characters to a string   srcPtr := Addr(source);   SetString(target, srcPtr, 5);   // Show what we have got   WriteLn('target now = '+target); end; Show full unit code    target now = ABCDE
