Re: Help!: of Swarm, Objective-C and

[William S. Shu]

Thanks for the valuable suggestions.  Most of the problems have "gone away".
Some others (probably even more naive) have surfaced, or rather, have risen
in importance:

1)    Is there any way of type-checking, at least at compile-time, that the
entries of a list (or any collections.h object) are of the same (or a
particular) type (c.f. templates in C++)?  (Writing code to check this seems
to entail duplicating methods of the list protocol!)


2) Swarm examples and Control Panel interaction:
    a)    Why can one not change parameters via the GUI windows in the
heatbugs (1.3.1) example -- in fact from all (most?) the examples?

    b)    In which objects/variables should the above values be kept?  How
can they be accessed from within a program?

    c)    One can also change methods from the windows, right? How does one
do that?  In which variables/methods are they kept or accessed from within a
program?

    d)    The start button on the control panel seems to mean "resume from
where you last stopped OR, INITIALLY, start from the beginning".  How can
one have the meaning of "restart -- perhaps from an earlier point in time,
possibly the beginning" without having to start a new program run.  This
provides a sort of roll-back facility or may be useful when you want to
tinker with parameters (possibly of sub-swarms only) without having to
restart the whole process!  (Perhaps viewing things this way is not
necessary, and there may be "swarm-inclined" alternatives for rollback.)
