What is the expected return value of this form?

    (format nil "'~A' <= logdate and logdate < '~:*'" 1)

I was expecting:

    "'1' <= logdate and logdate < '1'"

but I get 

    "'1' <= logdate and logdate < ''"

in both sbcl and clisp.

Check again! (CLHS 22.3.7.1) ~:* just backs up one argument.
Now if you actually want to print it again add a ~A

CL-USER 2 > (format nil "'~A' <= logdate and logdate < '~:*~A'" 1)
"'1' <= logdate and logdate < '1'"
