Artur:

I think this is a problem with the way in that  'loop foreach' treats
its arguments: probably first if they are two or more arguments all of
them are treated as strings, for a unique argument it checks if it is a
list or a string and act different in each case. A solution may be:

open denmark

list ttt1 = LRM IBO
list ttt2 = IDE LRY

loop j=1..2

    list x=ttt$j
    loop foreach i x

        sprintf astr  "%11s", "$i"
        print astr
    endloop
endloop
