[ncl-talk] 回复： Re: call Fortran in NCL

[Dennis Shea]

I think you have a hidden  illegal character.
There is a 'dos' character. Use dos2unix to eliminate the character.

ot there

%> WRAPIT getlatlon.stub

WRAPIT Version: 120209
A syntax error occurred while parsing:
LINKING
END WRAPIT

 %> dos2unix getlatlon.stub

dos2unix: converting file getlatlon.stub to Unix format ...

%> WRAPIT getlatlon.stub

WRAPIT Version: 120209
LINKING
END WRAPIT

+++++++++++++++
I do not know why you are reading in fortran.
It is easy in NCL
++++++++++++++++

  diri = "./"
  fili = "station.txt"

  ncol = 2
  nrow = numAsciiRow(diri+fili)  ; determine # or rows

  latlon = asciiread(diri+fili, (/nrow,ncol/), "float")
  lat    = latlon(:,0)
  lon    = latlon(:,1)

  print(lat+"  "+lon)
