This version of Logo is designed for a machine with adequate memory. It is not likely to be usable as the basis for a 64K microcomputer implementation. The interpreter was written primarily by Daniel Van Blerkom, Brian Harvey, Michael Katz, and Douglas Orleans. Thanks to Fred Gilham for the X11 code. Send comments by e-mail to bh@cs.berkeley.edu. The Unix distribution includes a shell script called "configure" that customizes Logo for your particular version of Unix. Just type the name "configure" at a shell prompt. The script performs various tests to see whether particular libraries, etc., are available. The configure script writes several files. The most important are makefile used to compile Logo config.h header file used by C source files Note: It also writes a file "config.cache" in which it remembers the results of its tests. If you copy the Logo source directory to another machine with a different version of Unix and try to recompile, you should remove config.cache before running configure. With these files in place you should be able to say "make" to the shell and get three results: logo executable Logo interpreter logolib directory with pseudo-primitives in Logo helpfiles directory with online documentation You can move the executable "logo" to wherever you want (e.g., /usr/local). Logo assumes that you will leave the directories "logolib" and "helpfiles" in the source directory! If you would rather not keep the source files online, and wish to move these subdirectories somewhere else, then instead of saying "make" you should say, e.g., make LIBLOC=/usr/local/lib/logo (If you have already said "make" before reading this, remove libloc.c before giving the make command above.) The distribution also includes the file "usermanual" which is a rather terse description of this particular Logo dialect for people who already know how to program in Logo. To install Logo you need merely move the file "logo" to wherever you want it. The files ztc* and mac* are for toy-computer versions of Logo. But if you are trying to compile for those machines you probably also need some extra help beyond what's in here. You can get complete PC and Mac versions by anonymous FTP from anarres.cs.berkeley.edu. ---------- Here are the special features of this dialect of Logo: Random-access arrays. Variable number of inputs to user-defined procedures. Mutators for list structure (dangerous). Pause on error, and other improvements to error handling. Comments and continuation lines; formatting is preserved when procedure definitions are saved or edited. Terrapin-style tokenization (e.g., [2+3] is a list with one member) but LCSI-style syntax (no special forms except TO). The best of both worlds. First-class instruction and expression templates. Macros. ----------
