logical expressions - is this a bug?

Hello there,

I'm not sure if this is a bug or a "feature" - but it seems that logical
variables are overwritten as soon as they are "reached" in a logical
expression.

Example:

This fails (c2 appears first on line 5, RHS)
c1=False
c2=True
do i=0,10
  c2=c2.and.c1
end do

This works (c2 appears second on line 5, RHS)
c1=False
c2=True
do i=0,10
  c2=c1.and.c2
end do

We are using NCAR Command Language Version 5.1.1

thanks,

Adrian
