Managing mode change

[garry23]

@a1ex

I've stumbled again 

What I'm trying to do is enter my script in any mode, ie M, Av or Tv, and in the script change/control both aperture and shutter speed, ie run the script in M mode.

Is there a way to switch modes in Lua?

If there is, I can't find it.

The alternative being to force the script to only run if in M mode.

As usual I'm hoping you have the answer 

Cheers

Mode change is not supported, as I had some issues with it in the past. For example, on 60D, I've got ERR70 in a software-switched shooting mode, but everything was OK when switching to that mode from the dial.

Might be doable, but I wouldn't enable it just because it seems to work; rather, I want to understand what caused the above issue.

I thought you might say something like that 

No problem, will restrict script to M mode.

BTW my use case was entering the script in Av mode and then changing shutter speed in the script.
