Stopping a macro

[Guest]

I just started experimenting with QM and it looks very useful. I made a simple macro that calls three other macros sequentially and repeats 100 times. It seems to work fine except that sometimes I would like to be able to stop it before it completes all 100 iterations but a haven't been able to figure out how. Any help would be appreciated.

rep 100
mac "macro1"
mac "macro2"
mac "macro3"


Thanks.
