I have read the following information in NCL Reference Manual


One very important thing to note is that all parameters are *passed by
reference* in NCL, meaning a change of a value in a variable within the
function changes the value of the parameter.

However, if a parameter is coerced before the function is called, changes
within the function *will not* be reflected in the parameter, because
coercion can only be applied in a single direction. A warning message is
given in this instance.


Can anybody give details about the statement *"....* if a *parameter is

*Thanking you in advance.*
