Moving floor up & down with 1 switch? (Hexen settings)

[bowserknight]

So I'm making a map in "Zdoom (Doom in Hexen Format)" and was wondering if it's possible with only one switch to make a floor lower, and after pressing it again, make it go back to its original height, and then lower again and so on. Kinda like a lift, but without the automatic part of it, just alternating between up and down with each push of the button. Hope you know what I mean. And if it's not possible, how do I even make it go back to its original position without being a lift or having any adjacent floors?

EDIT: I guess you could also achieve it with a script?

Yes, a script is the only way, either ACS or ZSCRIPT.
You'll have to toggle the state of a variable either on or off to achieve
the action (floor lower) and then a reversal (floor raise) and restart.

No reply in over two weeks,
so I don't know if he has worked it out for himself or if he is stumped

In any case, I had occasion to fiddle with this idea to move the floor and
ceiling of two sectors and came up with this
