You can do it, but a more flexible diagram architecture may be more
appropriate.
First, if you just want something quick and dirty, the buttons on top of
the window, the || button will pause the diagram and allow you to continue.
If you want one button to pause and continue, make it have mechanical
action of a plain switch, and somewhere in your F
or loop add a while
loop that executes until the Boolean is FALSE. If you press the button,
it will change to TRUE and stay there until you press it again. The
program will still be running, but the while loop will not finish until
the button is FALSE. Since the while loop is inside the for loop, the
for loop must wait for the while loop.
If you want something more flexible, look to using a state machine.
Have a state for generating and charting a number, a state that checks
the button, and a state that does nothing. Now make your state
transition logic do the appropriate states depending on the button.
