I think I may not have been clear. I am not asking for a macro that disables old line number support, I'm asking for resetting the old->new line number mapping table.
After a build in the process buffer (lets call this "PBuild"), I'm thinking that SlickEdit must be creating some kind of mapping table of old->new line numbers. Then when a user edits a file, it adjusts this mapping table.
Before any PBuild takes place, this mapping table probably doesn't exist, or is in some default state where "new line" = "old line" or "1-1" mode.
My request is to have a macro that allows me to clear this mapping table and put it back into 1-1 mode. This way when I initiate a build in the Output Window (lets call this "OBuild"), I can call this new macro to clear this mapping table.
Currently if I open SlickEdit, don't perform any PBuild, and do many iterations of Edit/OBuild, since there is no mapping table, double clicking in an Output Window error always takes me to the correct line. But after the first PBuild, this mapping table exists and I no longer go to the right line for subsequent OBuild error output. I'm requesting to have a way to put it back to the way it was before I did my first PBuild, where there the mapping table for that file is cleared and is in 1-1 mode.
An alternative solution could be to have a mode so that whenever I double-click on a line in the Output Window (not the process buffer), it always goes to the new line, but the Process buffer always goes to the old line.
