[ferret_users] repeat/range error

[Zibiao Zhang <zzhang@xxxxxxx>]

Hi All,
I have a ferret loop program as following:

let year_start = 2005
let year_end = 2006
let mon_start = 1
let mon_end = 12

repeat/range = 'year_start':'year_end':1/Name=yr
	(define symbol yy = 'yr';
	let m1 = if '($yy) EQ year_start' then mon_start else 1
	let m2 = if '($yy) EQ year_end' then mon_end else 12

	repeat/range='m1':'m2':1/name=mo
		(define symbol mm='mo';
		let mo = if '($mm) LT 10' then "0($mm)" else "($mm)"
		let outname = "($yy)" + mo + "15t.nc"
		let inname="archv." + "($yy)" + mo + "1500_3zt.nc"

		set data 'inname'
		list/file='outname'/clobber/i=200:450/j=800:1050/format="CDF" temperature
		can data 'inname'
	);\
)

When I ran it on windows based ferret, I got weired error message:
repeat/range = 'year_start':'year_end':1/Name=yr
**ERROR: unknown command qualifier: range= 'year_start':'year_end':1

Anybody knows what is going on?

THanks in advance.
