Enters the debugger in the current thread after steps line events occur. Before entering the debugger startup script is read.
Setting steps to 0 will cause a break in the debugger subroutine and not wait for a line event to occur. You will have to go “up 1” in order to be back in your debugged program rather than the debugger. Settings steps to 0 could be useful you want to stop right after the last statement in some scope, because the next step will take you out of some scope.
