Re: Why these two lines do not execute?

Wen,

It is hard to tell what the problem is because you have some weird line continuation characters below, and you have a lot of parentheses.

My guess is that you just have one too many parentheses below.

I suggest breaking up your "if" statement into more continued lines, so you can be sure you have the correct parentheses. Also, try removing some unnecessary parentheses.

For example, instead of:

> (.not. (ismissing(visib_full)))

You can simply do:

> .not.ismissing(visib_full)

and instead of:

> ((fog_full.eq.0) .and. (rain_full.eq.0) .and. (snow_full.eq.0) .and. (hail_full.eq.0))

You can have:

> (fog_full.eq.0 .and. rain_full.eq.0 .and. snow_full.eq.0 .and. hail_full.eq.0)
