Re: string plus string

x = asciiread("....", -1, "string")

nx = dimsizes(x)
do n=0,nx-1
    nf = str_fields_count(x(n), " ")
    if (nf.eq.1) then
        ss = str_split(x(n)," ")
    else
        aa = str_split(x(n)," ")
        ss = aa(0)+" "+aa(1)
    end if
     print(""+ss)
end do

or

ss = new(nx, "string", "No_FillValue")
do n=0,nx-1
    nf = str_fields_count(x(n), " ")
    if (nf.eq.1) then
        ss(n) = str_split(x(n)," ")
    else
        aa = str_split(x(n)," ")
        ss(n) = aa(0)+" "+aa(1)
    end if
end do

print(""+ss)
