Re: Assign Character Data to a Variable

Hi Bruce,
Sorry the documentation is not more clear, but character assignment using a small integer with the 'C' suffix is only available in NCL 6.0.0 or later.
Regarding a link to an ascii chart, starting with NCL 6.0.0, there is a procedure called 'show_ascii' that prints a table of ascii equivalent values:

ncl 4> show_ascii
                        The decimal set:
       0 nul 1 soh 2 stx 3 etx 4 eot 5 enq 6 ack 7 bel
       8 bs 9 ht 10 nl 11 vt 12 np 13 cr 14 so 15 si
      16 dle 17 dc1 18 dc2 19 dc3 20 dc4 21 nak 22 syn 23 etb
      24 can 25 em 26 sub 27 esc 28 fs 29 gs 30 rs 31 us
      32 sp 33 ! 34 " 35 # 36 $ 37 % 38 & 39 '
      40 ( 41 ) 42 * 43 + 44 , 45 - 46 . 47 /
      48 0 49 1 50 2 51 3 52 4 53 5 54 6 55 7
      56 8 57 9 58 : 59 ; 60 < 61 = 62 > 63 ?
      64 @ 65 A 66 B 67 C 68 D 69 E 70 F 71 G
      72 H 73 I 74 J 75 K 76 L 77 M 78 N 79 O
      80 P 81 Q 82 R 83 S 84 T 85 U 86 V 87 W
      88 X 89 Y 90 Z 91 [ 92 \ 93 ] 94 ^ 95 _
      96 ` 97 a 98 b 99 c 100 d 101 e 102 f 103 g
     104 h 105 i 106 j 107 k 108 l 109 m 110 n 111 o
     112 p 113 q 114 r 115 s 116 t 117 u 118 v 119 w
     120 x 121 y 122 z 123 { 124 | 125 } 126 ~ 127 del

Hope this helps.
