A new, better pad technique

Let's say you want to pad a number with leading zeroes, no matter how large it is. You can write out a bunch of @If statements or just always pad zeroes using a very large number. This code shows you how to pad a number if it's less then x but leave it alone if it's greater than x.

REM "The Code";
StringToPad := "12345";
StringLength := 4;
PadChar := "0";
UsualWay := @Right(@Repeat
(PadChar; StringLength) + 
StringToPad ; StringLength); 
MyWay:=@Repeat(PadChar;
@Max(StringLength-@Length
(StringToPad);0))+StringToPad;

REM "Sample outputs for testing";
@Prompt([OK];"UsualWay-Pad("+@Text(StringLength)+"): "+StringToPad;UsualWay);
@Prompt([OK];"MyWay-Pad("+@Text(StringLength)+"): "+StringToPad;MyWay)
