KORN SHELL : Reading file names with spaces

I need to write a script which sorts through folders and files and performs file management (e.g. rm) on certain files.  I wrote the names to a file in order to read them in one at a time.  Everything works fine until I run across files with spaces in them (which are generated from a Macintosh environment).

How can I read back the file names that contain spaces and do operations on these files without the ksh seeing to file names instead of one name with a space in it?

Easy enough...just put double quotes around the variable containing the filename when you use it.  Here's a simple ksh script that finds all the files in or below the current directory and executes "ls -l" on each one:

#!/bin/ksh

find . -type f -print | while read FN ; do
      echo "Found a file: $FN"
      ls -l "$FN"
# Note: without the double quotes above, this won't work!
done

----------------------------------------------------

I created a directory containing some files with no spaces in the names, and others with a space (lower-case filenames "a", "b", and "c" have no spaces; upper-case names "A A", "B B", and "C C" do).  When I run this script, I get:

dhm@eagleone[38]$ ./test.ksh
Found a file: ./foo/a
-rw-rw-r--   1 dhm      webvisio        0 Jul  4 10:53 ./foo/a
Found a file: ./foo/b
-rw-rw-r--   1 dhm      webvisio        0 Jul  4 10:53 ./foo/b
Found a file: ./foo/c
-rw-rw-r--   1 dhm      webvisio        0 Jul  4 10:53 ./foo/c
Found a file: ./foo/A A
-rw-rw-r--   1 dhm      webvisio        0 Jul  4 10:53 ./foo/A A
Found a file: ./foo/B B
-rw-rw-r--   1 dhm      webvisio        0 Jul  4 10:53 ./foo/B B
Found a file: ./foo/C C
-rw-rw-r--   1 dhm      webvisio        0 Jul  4 10:53 ./foo/C C
Found a file: ./test.ksh
-rwxr-xr-x   1 dhm      webvisio      100 Jul  4 10:57 ./test.ksh
