function UserCall($msg) {

# examples include putting a message in the conclusion, changing databases,
# changing directories, retrieving CSV rule sets from the internet...

### UserDebug() - user debug interface called from a rule set
function UserDebug($msg) {
# globals
global $exp;

# get the value of control values or arrays

either here or in an alternate interface function.
For example the interface can be with a browser,
web page, or another program.

function Finalize() {
# globals
global $exp;
