1.  Overview
============

The sample program in this directory uses the "toupper" and "tolower" functions
to show conversion from upper to lower case and visa versa.

These functions are culturally sensitive because most locales do not have case
in their alphabets.  Further, accented characters must be converted to the
proper character.

Note: Some of the upper case characters for accented characters are not shown
      properly in the US 437 code page.  If the program were to be run on a
      machine running the code page for the locale, the character would display
      correctly.


2.  Files in this directory
===========================

File            Purpose
------------------------------------------------------------------------------
ul.c            Source code for the ul sample program.
ul.def          Definition file needed for compiling the program.
ul.mak          Make file used to compile the sample.
ul.exe          Compiled version of the ul sample.

build.cmd       A command file which will compile and link the sample program.
read.me         This file.


3.  How to run the sample program
=================================

The following steps show how the program can be run.

     1) Run the \i18n\bin\new_vars command file (or have the environment
        variables already set).

     2) Set the value of either LC_ALL or LANG to: En_US (US English).

          Ex:   set LANG=En_US

     3) Execute the ul.exe program.

          Ex:   ul

     4) Experiment with changing the values of the LANG environment
        variable.  Try the Fr_FR locale to see the difference in the
        results.  Before you run the program in french, change the
        current codeset "chcp 850" so all of the characters display
        correctly.  When you're done, change the code set back to 437.


4.  How to compile the sample program
=====================================

NOTE: The sample program is already compiled for you.  If you want to see the
 behavior of the program, you can just run it.  The following instructions
 are needed only if you want to modify the program and recompile it.

To compile the sample application:

     1) Make sure that the CSET/2 compiler and OS/2 toolkit are installed
        correctly on your system.

     2) cd to the directory which contains the is source files.

     3) Type "build" at the command prompt.


5.  Notes
=========
1. Some of the upper case characters for accented characters are not shown
   properly in the US 437 code page.  If the program were to be run on a
   machine running the code page for the locale, the character would display
   correctly.

2. Note that these functions are similar to the functions in the "ulcase_w"
   directory, only these operate on characters, not wide characters.
