Re: a puzzle with getenv function

OK, this is indeed rather bizarre. I'm filing a bug report on this. Also, it evidently has nothing to do with getenv(), per se:

ncl 0> OK=True
ncl 1> foo=new(1,"logical")
ncl 2> OK=OK.and.(.not.ismissing(foo))
ncl 3> OK=OK.and.(.not.ismissing(foo))
fatal:Execute: Error occurred at or near line 3

And also,

ncl 0> OK=True
ncl 1> OK = OK.or.(.not.ismissing(getenv("dummy")))
fatal:Execute: Error occurred at or near line 1

And this one..

ncl 0> OK=True
ncl 1> OK=OK.and.(ismissing(getenv("dummy")))
ncl 2> OK=OK.and.(ismissing(getenv("dummy")))
ncl 3> OK=OK.and.(ismissing(getenv("dummy")))
ncl 4>
