Hi,

in sunpos.inc, I find several statements of this form:

|#if (0<M<360)
|    ...
|#end

I can remember, that -- many years ago -- I read somewhere about this 
'(value1 < variable < value2)' construct. But I cannot recall, what the 
construct does.
In the POV-Ray documentation, I could not find an explanation of this 
construct. If it is there, the explanation seems to be hidden very 
thoroughly. :)

Could anyone please tell me, what '(0<M<360)' does?



Many thanks in advance,
