XLISP This PD file contains the C sourse of David Betz' XLISP v1.4. It is free, copyable for non-profit use provided you preserve the details of authorship. The manual is terse, a reference manual. For a tutorial introduction, use Winston's LISP, 2nd edition, for Addison-Wesley. Most of the LISP described in that book is in XLISP. XLISP v1.4 is essentially a small core set of Common LISP. The object oriented features of XLISP are NOT part of Common LISP, however. In the PD file, C soure files are called C and the single header file is called XLISPH. The manual is in MANUAL. You will probably need to edit the C source a little. It expects the header file to be called xlisp.h at present, and it expects LISP files to be called .lsp. In this PD file, the demo and startup files are called LSP. There are various '#ifdef ...' statements meant to cater for different compilers. You should look for these and see how your C compiler differs at those points. You are on your own, now - good luck. Just compile and link the files together....
