Greetings NCL'ers,
    Maybe this is a completely silly question, but is there an NCL
built-in to convert a variable of type string to a variable of type
logical? I suppose it would be trivial to write such a function, but I
couldn't seem to find one. Simply assigning a logical to the value of a
string ("True" or "False") doesn't work (see below). According to the
it doesn't seem that string types are coercible to anything else.

ncl 0> stringvar = "False"
ncl 1> logvar = new(1,logical)
ncl 2> logvar = stringvar
fatal:Assignment type mismatch, right hand side can't be coerced to type
of left hand side
fatal:Execute: Error occurred at or near line 2
