Seems like the easiest approach would be for you to implement versions of READ-INTEGER, READ-FLOAT, etc. If the source for these functions in CLisp is available your work might be 90% done for you. There's no way to directly do what you want in ANSI Common Lisp (why is why Clisp has its own functions), and I don't know of corresponding functionality in Corman, although it might be there. ------------------------ Yahoo!
