Re: stringtochar function

The character you're seeing is a NULL character. This will always be appended when you call stringtochar.

I believe the reason for this NULL character is for the case where you give it an array of strings. Since each string may be a different length, it becomes
necessary to have something that denotes the actual end of each string

To correctly get the string length, you need to subtract 1:

  s = "123456789"
  c = stringtochar(s)
  clen = dimsizes(c) -1
  print("length of c = " + clen)

(0) length of c = 9

This cause the unmatched dimension size error while I tried to assign the char array to a variable (with a dimension of the string length). I donot understand how the "0x00" relates to the missing value of original string (as detailed on the ncl webpage of the stringtochar function). And how can I avoid it? Can someone clarify for me. Thanks!
