SwapIfLower

SwapIfLower NumericVar1, NumericVar2

Parameters:     NumericVar1 = first numeric variable     NumericVar2 = second numeric variable

Returns: NONE

SwapIfLower performs a conditional swap betweem two numeric variables. SwapIfLower checks If NumericVar1 is lower than NumericVar2, if so, it swaps the contents of the two variables. if not, they are left unchanged.      If the data typse of both variables are not the same, PlayBASIC will cast them automatically. So you can swap between an Integer and Float variables, But that's not recommended. FACTS:       * SwapIfLower cannot use string variables.       * SwapIfLower performs a conditional exchange between two variables, so it's short hand for the following.    ; check if A is less  than B. If so, perform swap them.   If A<B    ; Do swap      Temp=A    ; Store A in a temp varibale      A=B  ; Move the value in B into A Variable      B=Temp   ; Move the Temp Variable into Temp   EndIf    is the same as,    ; Do swap   SwapIfLower A,B    Mini Tutorial:    ; define two variables   a = 10   b = 100    ; swap a and b if a is less than b   SwapIfLower a,b    ; print the variables   Print a   Print b       ; Display the Screen and wait for the user to press a key   Sync   WaitKey    This example would output.      100   10
