[ncl-talk] fatal error: "Assignment not supported for left-hand type"

[franz]

Dear ncl-team
    I'm using the ncl 6.1.2 on imac Darwin 64bit
    I got this fatal error: "Assignment not supported for left-hand type"
    and I don't understand the source of this error.

   Below there is part of my code (where I think NCL does not like)
   (I putted printVarSummary(...) to shows the info of the suspected 
variables)
