[ncl-talk] Fw: read and plot multiple files with different sizes

[Dennis Shea]

NCL is a strongly typed language. There are certain operations that are not
allowed.
---------------------
By default, NCL is a strongly typed language. It will not allow certain
operations.

 You can use the NCL *reassignment operator  *  *:=*

Consider:

float  a(10)
double b(10)
float c(30)

By default:
    a  = b     ; NCL will issue a FATAL error; it will not allow a double=>
float because information may be lost
    a := b     ; NCL will truncate

    a  = c     ; FATAL ... it will not allow an array of size 30 to be
reassigned to an array that is size 10
    a := c     ; NCL will overwrite

So I suggest going over your script and anyplace you this a size and or
type might change ... use the := syntax.I
