Re: could I get the string "abc" from a string of "abc.dat" in NCL?

Lin,

You can use stringtochar() and chartostring() functions. See an example:

> a="12345"
> b=stringtochar(a)
> print(b)

Variable: b
Type: character
Total Size: 6 bytes
6 values
Number of Dimensions: 1
Dimensions and sizes: [6]
Coordinates:
(0) 1
(1) 2
(2) 3
(3) 4
(4) 5
(5) 0x00

> c=chartostring(b(0:2))
> print(c)

Variable: c
Type: string
Total Size: 4 bytes
1 values
Number of Dimensions: 1
Dimensions and sizes: [1]
Coordinates:
(0) 123

I hope it helps you!
