(pdf:add-fonts-to-page helvetica)
(pdf:in-text-mode
(pdf:set-font helvetica 36.0)
(pdf:move-text 100 800)
(pdf:draw-text "CL-PDF: Example 1"))
(pdf:translate 230 500)
(loop repeat 101
for i = 0.67 then (* i 1.045)
do (pdf:in-text-mode
(pdf:set-font helvetica i)
(pdf:move-text (* i 3) 0)

I would think you just need to paste the example code into the REPL buffer and
it should just run. The MAIN function is defined, and (main) should invoke it.

What have you tried?
What didn't work?

REPL = Read-Eval-Print-Loop. It is the main interaction with Lisp. For example if you were to type
(+ 1 3)
it should print 4

Thanks a lot,as your answer,I did it .these code can be run and generate "ex1.pdf",I'm poor with the emacs ,I think.
thanks again.
