Re: str_split

Hi Mark,

You uncovered a bug in that code. Could you replace the function named
string_to_array(org_str) with the following, please?
This function is defined just above "str_split". Note that you
need to use NCL version 5.1.1 or later, as I am using the built in
function "str_fields_count" in this version to get the number of
fields.

Thanks for letting me know about the problem..

function string_to_array(org_str)
begin
  str=org_str
  if .not.isatt(str,"separator")
    str@separator=","
    cmd="echo "+str+" | tr [:blank:] ',' "
    str=systemfunc(cmd)
  end if
  if str@separator .eq. " "
    sep="\ "
  else
    sep=str@separator
  end if
  istr = stringtoint(str_fields_count(str,sep))
  str_arr=new((/istr/),"string")
  do i = 0, istr-1
    CMD="echo "+str+" | awk -F"
    CMD=CMD+sep+" '{print $"+(i+1)+"}'"
    str_arr(i)=systemfunc(CMD)
  end do
  return(str_arr)
end
