Re: [ferret_users] string composition

["Ansley C. Manke" <ansley.b.manke@xxxxxxxx>]

I agree this seems like a bug, and I'll have a look at this. Addition of 
strings is one way to work with them, but for combining two strings, the 
STRCAT function is the most reliable:
 
 
yes? list/nohead strcat(v1.units, v2.units)
        "m/smmol C m-3"
 
A variation on your last command could be this, creating a single string.
 
yes? list/nohead "`v1.units` + `v2.units`"
        "m/s + mmol C m-3"
