Agenda[ masterclient, control-data

Minutes[ 

Masterclient:
Current problem: when calling C++ out of Java that binds to Orbix, a
Java exception occurs.
Woody will try out some other variants. 
Possible way to go: C++ master that calls Java code (original design).

Dataflow and controlflow:
We take the current approach. User-data of simple CHAIMS types can
become control-data. In CLAM, we allow comparison of simple CHAIMS
types. Consequence for the compiler: whenever the compiler comes accross
a comparison (e.g. "a<b"), it has to find out if 'a' and 'b' are
gentypes or not, and if they are gentypes, it has to extract the value
before generation the appropriate comparison in C. Possible run-time
error: a wrong megaprogram may attempt to compare complex types. The
generated client should realize that and issue an error-message before
aborting.

Preperation for next week (lm, ns, wp):
Tasks to be accomplished for the demos.
