It's never too difficult :)
The challenge is the fun!

One simple change..

exit_code = walk_dir(name,routine_id("look_at"),FALSE)

aside from changing the first argument to just name, notice that I changed TRUE
to FALSE. see below


Your look_at() function is not quite right still.
I had assumed you fixed it yourself, since your were satisfied with the code I
posted the other day.

It doesn't unindent, when it leaves a subdirectory.

Using the function the way it is, you will get:
C:\
  C:\subdir1\
    C:\subdir1\file1.txt
    C:\subdir1\subdir2\
      C:\subdir1\subdir2\file2.txt
      C:\subdir3\
        C:\subdir3\file3.txt

What you really want is:
C:\
  C:\subdir1\
    C:\subdir1\file1.txt
    C:\subdir1\subdir2\
      C:\subdir1\subdir2\file2.txt
  C:\subdir3\
    C:\subdir3\file3.txt


Here is the function ya need..
function look_at(sequence path_name,sequence entry)
 integer ret
    ret = 0 -- default exit code
    if k=0 then
       -- it's not a good idea to put multiple statements on one line
       -- the 2nd statement is easily missed
       printf(1,"%s \n\n",{path_name}) k=1
    end if
    puts(1,"\t")
    if find('d',entry[D_ATTRIBUTES]) then
       puts(1,"\n\t\t<SUB DIR> ")
    end if
    printf(1,"%s%s\n",{repeat('\t',tabs),entry[D_NAME]})
    if find('d',entry[D_ATTRIBUTES]) then
       puts(1," \n")
       tabs += 1
       -- recurse into subdirectory
-- we need to walk the subdirectories ourself so we know when they are
       finished
       ret = walk_dir(path_name&"\\"&entry[D_NAME],routine_id("look_at"),FALSE)
       tabs -= 1 -- unindent
    end if
    return ret
end function

-- Using FALSE instead of TRUE, walk_dir() will traverse only the top-level in
the specified directory.
-- Subdirectories are traversed via the look_at() function.

exit_code = walk_dir(name,routine_id("look_at"),FALSE)


Hopefully I got it right this time.
