XLISP is available as part of my WINTERP package on the MIT X11r4 contrib
tape. Specifically, you'll find it in the
contrib/clients/winterp/src-server/xlisp directory. Examples are in the
 ...winterp/examples/xlisp-1.6
 ...winterp/examples/xlisp-2.0 directories.
Information on compiling the source is in ...winterp/doc/README.XLISP

However, the version of WINTERP distributed on the X11r4 tape is not the
version I wanted distributed -- I suggest you don't even bother with it.

If you want the latest version of WINTERP+XLISP, just get it directly via
anonymous ftp from expo.lcs.mit.edu directory contrib/winterp File
winterp.tar.Z; There's also other files in that directory. Poke around.

The following were added to XLISP 2.1, that were not in 2.0:
"DEFSTRUCT" "%STRUCT-TYPE-P" "%MAKE-STRUCT" "%COPY-STRUCT" "%STRUCT-REF"
"%STRUCT-SET" "ASIN" "ACOS" "ATAN"

No sign of ln...

PS: note that I added the following primitives to the WINTERP distribution
of XLISP. Note that many of these are unix specific: "FSCANF-FIXNUM"
"FSCANF-STRING" "FSCANF-FLONUM" "COPY-ARRAY" "ARRAY-INSERT-POS"
"ARRAY-DELETE-POS" "SYSTEM" "POPEN" "PCLOSE"

Please post these diffs.
