    About the axlGetParam command Reply

    I want to get the TextBlock attribute by variate.

    1. The general situation: OK

    p=axlGetParam("paramTextBlock:2")
     p->??
    =>
    (objType "paramTextBlock" width 0.584 photoWidth
        0.127 name "2" lineSpace 0.991
        height 0.787 charSpace 0.203
    )


    2.
    n=2
    p=axlGetParam("paramTextBlock:n")
    p->??
    =>(objType "paramTextBlock")

    3.
    procedure( Text(x "n")
    axlGetParam("paramTextBlock:x")
    )
    Text(2)->??
    =>(objType "paramTextBlock")

    The result of the 2nd and 3rd situation are not correct. why? how can I get it?

    The problem is that you are passing a string to the axlGetParam procedure.

    Because "x" is inside of double quotes,  you are passing a string "x" rather than the evaluation of the variable x.

    use sprintf, and I would check to make sure that x is an integer:

    procedure(Text(x)
       when(integerp(x)
          axlGetParam(sprintf(nil "paramTextBlock:%d" x))
       )
    )

    This should return the param or nil (when invalid input).

    Ok.

    It means that I can use sprintf to convert  number type to string type.

    haha, thanks.
