Sorry, I had a typo in my solution. You have already found the offending line, the comma is the error. It should read:

Code:
print - "$line" | read word line

and, when you call the whole script "tokenize.ksh", you could use it like:

Code:
cat anyfile | tokenize.ksh | some_script_using_tokens.ksh

If you meant by "tokenizing" that you want only the first word of each line going to the output (sorry, but that wasn't clear from the beginning, at least not for me), replace the while...done-loop by a sinqle

Code:
print - $line | read word junk
print - "$word"

The way the "read"-statement works is: put the first word encountered to the first variable, the second word to the second variable, etc. If you run out of variables put the rest of the line to the last variable. This means "read line" will read the whole line, regardless of how many word are in it, "read word line" will put the first word to $word, everything else to $line.

Since you mentioned that "echo 111 222 | read word line" doesn't work either I suppose your Kornshell implementation is as faulty as was my script. On my system (various AIX 5.x versions) it works perfectly.
