Printing without linefeed?



I'm running a long program, and every now and then I'd like to print
something, just as an indicator of how much it's done.  The "print" command
gives me a linefeed, which I don't want.  The lisp command "?write" might
work, if I could work out how to include a space as well; ?write(i," ")
doesn't work.  Also, I don't seem to be able to use ?write in a program.
Are there other options?

Thanks,
Alasdair
