OK thanks. For clarity I'm assuming the leading C in CMinMaxClass is a typo?

I've come across some curious behavior. This was actually working for me last week:

class MINMAXCLASS
     local min
     local max  
endclass

global min_max_t = new (MINMAXCLASS)

class WSCLASS
    local status
    min_max_t temperature
    min_max_t windspeed     
endclass

global ws = new(wsclass)

ws.temperature.max = 10

But now gives an error. But if I do this:

class MINMAXCLASS
     local min
     local max  
endclass

class WSCLASS
    local status
    temperature = new (MINMAXCLASS)
    windspeed   = new (MINMAXCLASS)
endclass

global ws = new(wsclass)

ws.temperature.max = 10

Then change to the first code, it works with no error message. Am I just grabbing some garbage value that hasn't been collected yet?

Is it possible to nest classes in DF?

class MINMAXCLASS
     local min
     local max  
endclass

class WSCLASS
	local status
	MINMAXCLASS temperature
	MINMAXCLASS windspeed	
endclass

global ws = new(WSCLASS)

ws.temperature.max = 10
