It is possible. If the datalog is created from outside the program (i.e.
RCXcc) then my program correctly logs the IR messages. The problem I'm
having is that I cannot get the RCX to create the datalog from within the
program.
From Dave's documentation:
Values can then be added to the datalog using AddToDatalog(value). When the
datalog is uploaded to a computer it will show both the value itself and the
source of the value (timer, variable, etc). The datalog directly supports
the following data sources: timers, sensor values, variables, and the system
watch. Other data types (such as a constant or random number) may also be
logged, but in this case NQC will first move the value into a variable and
then log the variable. The values will still be captured faithfully in the
datalog, but the sources of the data may be a bit misleading.

| (...) Have you tried putting in a Wait command after creating the Datalog and before you start using it? It must take a few milliseconds to set up. Just my .001 cents after taxes...

A careful examination of the DataLogNext command in the beta SDK documentation shows that the command is quite limited and that you can only log (global) variables, timers, sensor values and the watch/clock.
