[proFit-list] Dynamically Adding Variables

[pro Fit Support]

Andrew

Yes, you can do that. Basically, you call SetFunctionProperties for  
nrParameters in Check. Here is an example, which basically sets the  
number of parameters to the value you enter in a[1].


function MyPoly;

  var i;

function Check;
begin
	if pNumber = 1 then				// if a[1] has changed
		if (a[1] < 1) or (a[1] > 100) then
			Check := bad
		else
		begin
			SetFunctionProperties(function '', nrParams a[1]+1);
			Check := update;			// redraw the parameter window
		end;
end;

begin
	y := 0;
	for i := 1 to a[1] do
		y := x*y + a[i+1];
end;
		
	
You can also set the names of the parameters using  
SetParameterProperties,

Good luck

Kurt
