today class we are looking at some String routines. Routines to
convert Strings to upper Case, lower Case,etc.

Remember to turn off CHECK String Var PARAMETER LENGTHS With {$V-}
beFore calling the String Procedures. Turn it back on after calling
this proc.

{--[UPPER CASinG StringS]--}

Procedure UPCaseL(Var CString:String);

Var I:Byte;

 begin
   For I:=1 to LENGTH(CString) do CString[I]:=UPCase(CString[I])
 end;

{--[LOWER CASinG CharS]--}

Function DWNCase(DWNCH:Char):Char;

begin
if ('A' <= DWNCH) and (DWNCH <= 'z') then DWNCase:=CHR(orD(DWNCH)+32)
end;

{--[LOWER CASinG StringS]--}

Procedure DWNCaseL(Var CString:String);

Var I:Byte;

begin
  For I:=1 to LENGTH(CString) do CString[I]:=DWNCase(CString[I])
end;
