Getting variables from New Window in JMP

[#1]

I've converted a column dialog() command to a New Window() display tree, and I'm having trouble with getting some of the data out of the dialog window.  Ideally, I just want to grab the columns specified in the dialog window (Y and grouping variables) as well as a radio button setting and a checkbox state and a text edit box value. I was hoping to just preload this into some variables and load a function, but I can't even figure out how to get the variables from within the display tree, as the "Show(yList)" command within the ButtonBox("OK", ) shows an empty list.

Here's the function declared at the top of the script:

startAnaFn = Function ({x},

show(numParam);

show(yList);

Show(gList);  

);

Here's a shorter version of my dialog:

anaDialog = new window("Select Parameters To Analyze",

					vlistbox(
						colListY = ColListBox(width(lbWidth),nLines(6), minitems(1)),
						checkObj=check box({"Use inverse of Y Selection"},<<Set(0,0)),
					),

numParam = text edit box("20"),

	hlistbox(
	textbox(" "),
	ButtonBox("Ok",
		::yList = colListY << get selected;
		show (yList); // <-- this does not show expected data either
		gList = colListG << get selected;
		anaDialog << close window;
		startAnaFn(1)),
	textbox("  "),
	ButtonBox("Cancel", anaDialog << close window),

    ),

);

PS: If this is a JMP forum, why does it assume pasted JSL code is in a table format?

I figured it out. I was using the wrong kind of "get" statement. Here is what worked:

yParamNames = colListY << get Items;

groupNames = colListG << get Items;

numParamVal = numParam << Get(numeric value);

invertY = checkObj << get;

radioRes = radioSel << get;

anaDialog << close window;

startAnaFn(1)),

But I have another question.  yParamNames returns the list in string format:  {"column 1 name", :column 2 name", etc}.

How do I convert this to {:column 1 name, :column 2 name, etc} format?

Thanks

uggh, here is my ugly hack.  I would appreciate if anyone can provide a more elegant solution.  I don't know what it is with JSL but it continues to baffle me.

yParamList = {0};

// select all cols

for (i = 1, i <= ncol(dtData), i++,

    column(i) << set selected(1);

    );

fullList = dtData << get selected columns();

yParamList = {0};

for (i = 1, i <= n items(fullList), i++,

    for (k = 1, k <= n items(yParamNames), k++,

        if( char(fullList) == yParamNames, yParamList = fullList; break());

    );

);

show(yParamList);
