I assumed you didn't want to do that.

I see no controversy. I too would welcome any input on TSR development though.

Nah, as I mentioned my assumption was wrong. While in DOS (potentially in code messing with MCBs itself: 21.48 or 21.4A or 21.5803 or 21.4B or 21.67) TSRs must not alter MCBs. Exceptions to this might exist, for example, I think a TSR can probably free its own MCBs at any time without risk.

Don't we all?
