2.3 I would like to know if there is a way to "erase" the REDO stack? For security reasons I would like to prevent sensitive commands from being seen by a LISTREDO command.
Either
:setvar hpredosize,0
or
:setvar hpredosize,1
followed by
:setvar hpredosize,n
where "n" is the size you normally use, will do the trick.
Obviously this could be set up as a UDC or command file, if it is something you do often.
