It looks like this should work

set_param('path/to/block', 'sw', '0')
set_param('path/to/block', 'sw', '1')

I found the names of the block parameters using this command, and just picked the one that seemed likely:

>> get_param(gcb, 'DialogParameters') % select the block first with the mouse

In version 2020A, for a manual switch (assuming it has just been selected)

get_param(gcb,'DialogParameters')

returns only the parameters varsize and SampleTime.

It seems that this 'sw' parameter does still give the switch postion, but where is this documented?

In particular is there a command similar to get_param(gcb,'DialogParameters') that would list this type of "hidden" parameter, or is there somewhere it would be listed in any of the documentation? I couldn't find it.

Thanks
