May I know if any command is available in SenseTalk to check a variable or value is of type String/text, Rectangle, list, etc. Appreciate any help.

How about writing a function using "Is A" operator?

Thanks, this helps. I was trying like text, string, etc… didn’t try letters :slight_smile: .

Here is the code for determining if a variable contains a rectangle.

put (0,0,460,120) into myRectangle
put VerifyRectangle(myRectangle)

//A rectangle is defined as a four item list in which each is numeric
to VerifyRectangle myRectangle

	put myRectangle is a list into tfList
	if tfList is false then
		Return false
		Exit Handler
	end if
	
	put the number of items of myRectangle is 4 into tfNumberOfItems
	if tfNumberOfItems is false then
		Return false
		Exit Handler
	end if
	
	repeat with each item of myRectangle
		put IT is a number into tfNumeric
		if tfNumeric is false then
			Return false
			Exit Handler
		end if
	end repeat
	
	return true
end VerifyRectangle

Unfortunately, that’s doing it the hard way (and doesn’t account for the fact that a rectangle in SenseTalk can be either a list of 4 coordinates or a list of 2 points). Keiichi_Yamamoto had the right idea – just use the is a operator:

put [[0,0],[460,120]] into myRectangle
put myRectangle is a rectangle --> True
