"Here document" in shell subroutine fails

If I try to do a “here document” in a shell subroutine, like this:

routine ()
{
cat <<-DONE
this is a test
of a here document
DONE
}

routine

I get an error message like this:

/tmp/sh1491500: cannot open (No such file or directory)

If I do the same in the main body of the shell script, for instance, by just
removing the “routine ()” from the above, it works just fine. Can anyone
shed some light on this?

Thanks,

Kevin

I believe that the DONE must be on a line by itself with no white space
before or after it.

When this does work for you, was it still indented?
Try not indenting it.

I’ll mention this in the docs for ksh.

You know, I wondered where this question went. My apologies for
misposting…
