Add in-line edition to the Exp environment so that you may edit the input environment tree directly in the initial environment view. The centaurlanguage command generates everything necessary to do so. You need only edit the file: contrib/Exp/pprinters/pprinters.rdb
and change the resource:
Centaur.Exp.ppml.std.Package: (env basic)to:
Centaur.Exp.ppml.std.Package: (line env basic)
Then compile the pretty printer by running ctmake in the subdirectory line.
You must reset resources and redraw any ctedit containing an Exp program to account for the change. Please consult the edition manual in the Mantle for information about in-line edition.
