Re: how to indice the data arrays in file by variable?

Please read the mini-Language Manual at
     http://www.ncl.ucar.edu/Document/Manuals/

Also, peruse the Reference manual

---
As described in the manuals:
   (1) NCL indexing (subscripts) are 0-based like C, C++, ...
   (2) Using [...] is not correct ($vNames[1]$ ==> $vNames(1)$ )
   (3) When using strings via -> you must enclose the string with $
   nNames = dimsizes (vNames)
   do i=0,nNames-1
      flvar = gbfile->$vNames(i)$
      printVarSummary(flvar)
      delete(flvar)             ; size and shape may change
   end do                       ; space between 'end' and 'do'

http://www.ncl.ucar.edu/Document/Manuals/>     this script failed for 
“gbfile->vNames" ，vNames should be the name
