Dear Lucius,

I hate doing this to you again, but your trim function chokes on empty
strings and on strings consisting entirely of white space. Sorry. jiri


function trim(sequence s)
    -- trim 'white space' from both ends of string s

    integer c,i,j,len
    len=length(s)

    -- left trim:
    i=1
    while i<=len do
        c=s[i]
        if c=32 or c=9 then i+=1
        else exit
        end if
    end while

    -- right trim:
    j=len
    while j>=i do
        c=s[j]
        if c=32 or c=10 or c= 13 or c=9 then j-=1
        else exit
        end if
    end while
    return s[i..j]
end function -- trim
