Outdated egg!
This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.
If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Notes:
- Arguments of type CHAR may be either characters or integers (the caracter code)
- Procedures that normally return an error code are checked, and a condition of the kind (exn curses) is raised.
- The ...printw procedures accept printf style format-strings (not the C printf, but the printf in Chicken's extras library unit).
