[vtcl-user] exit command & state change

[Brent Maxwell]

I am attempting to put a stop button on a vtcl interface to halt the execution of a routine running under vtcl, but the exit command seems to be disabled...is there any way around this?   Also, I would like to change the state of a button from active to disabled automatically during the execution of my procedure...how would I go about doing this?   Thanks, Brent   Brent Maxwell Wayne State University
