Dear Ferreters,
I am using ferret on XP. I have equally spaced daily data in time (30days*
12months* 30years). I would like to eliminate everything but data of january
over the years i order that i could do other things with the january data.
I tried looking it up in the archives and I tried with the following but
have not succeeded yet:
-----------------
repeat/l=1:10800:1 (let precip2=if ((`l` ge 1 and `l` le 30) or (`l` ge 361
and `l` ge 390) or (`l` ge 721 and `l` le 750) or (`l` ge 1081 and `l` le
1110) or....(and so on)....) then precip else precip*0.0)
-----------------
Does anyone can help me?
