Re: filevarattdef - IO/API

Sorry, there is not enough information.

Are you writing character variables to the netCDF file?

Just FYI

ncl 1> s = "test"
ncl 2> c = stringtochar(s)
ncl 3> print(c)

Variable: c
Type: character
Total Size: 5 bytes
             5 values
Number of Dimensions: 1
Dimensions and sizes: [5]
Coordinates:
(0) t
(1) e
(2) s
(3) t
(4) 0x00 ; NCL adds the NULL to char variables

ncl 4> nc = dimsizes( c )
ncl 5> cNew = c(0:nc-2)
ncl 6> print(cNew)

Variable: cNew
Type: character
Total Size: 4 bytes
             4 values
Number of Dimensions: 1
Dimensions and sizes: [4]
Coordinates:
(0) t
(1) e
(2) s
(3) t
