# Regarding individual entries:
|

#
|

# IOCCC winning entry code may not work on your system. Even with standards,
|
||||
# conditions and build environments change, especially when it comes to more
|
||||
# extreme code such you might find in an IOCCC winner. Moreover, what was
|
||||
# allowed and liked in one IOCCC contest may no longer be liked/allowed in
|
||||
# later IOCCC years.
|
||||
#
|
||||
# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
|
||||
#
|
||||
# GitHub pull requests are welcome:
|
||||
#
|
||||
# If you have a patch that might make running an entry work in modern Unix-like
|
||||
# environments, please create a GitHub pull request for the IOCCC judges to
|
||||
# consider.

# Suggestions and corrections regarding Makefiles, winning author information,
|

# fixing typos in remarks, and code patches are welcome via opening a GitHub

Basically, the lisp interpreter is good for some basic math operations, and
|
||||
for running itself. To do the latter, try this:
|
||||
|
||||
./lispob < lispob.c > lispob2.c
|
||||
diff lispob.c lispob2.c
|
||||
```sh
|

./lispob < lispob.c > lispob2.c
|
||||
diff lispob.c lispob2.c
|
||||
```
|
||||
|
||||
The program can also be run from an implementation of common lisp. To do
|
||||
this, run the common lisp compiler and then type the following command:
|
||||
|
||||
(load "lispob.c")
|
||||
```
|
||||
(load "lispob.c")
|
||||
```
|
||||
|
||||
The source code of lispob.c will be printed.
