ASCII Package for Informix

If your version of Informix is old enough not to support the CHR() and ASCII()
functions as built-ins, you can use this code to provide the functions instead.

You get:

* ascii.sql - stored procedure to give ASCII code corresponding to a given character
* ascii.unl - data for the ASCII table
* asciitbl.sql - definition for the ASCII table
* chr.sql - stored procedure to give the character (CHR) corresponding to a given number
* mkascii.sql - SQLCMD script to load the above into a database

Ideally, you should upgrade to a newer version of Informix.
