Could it be possible to write reactors using Autolisp?

I mean, not only reactors, but functions able to stand by stealthily (it's the right word?) wainting for events. And if so, how?

Pepe there are many lisp reactor examples here at the swamp. :)

Thank you for answer, CAB.

I think I was misunderstood (probably my poor, rusty english). I know I can use reactors in Autolisp, but I mean if I can write new types of reactors using Autolisp (not using 'VLR-s').

As far as I know, reactors are stand by functions waiting steathily (I insist  :roll:, It's that the right word?) for events, and I only can use Autolisp for 'one target' (I just can't find them another name :oops:) applications. So, lets suppose I want to write a new reactor that fires only if, let's say, anyother variable than the ones controlled by VLR-SYSVAR-REACTOR, changes, or a stealth function written in Autolisp that beeps if it's 12 o'clock while i'm working with autocad.

All you have to work with are the built in reactors.
You can get creative with the reactors you have to work with & do most things.
You may have more options with other programing languages line NET but I'm not familiar enough to
comment on them.

For an alarm clock you could use a combinations of reactors which look up the time on each call
to them. The same can be true for a variable that is not watched by the VLR-SYSVAR-REACTOR.
The potential to slow down ACAD is there but if you function were small and fast it would work.
You just have to use your imagination to find a solution.  :-)
