DGP There is no command in Tk called [pack-old]. Never has been. There is a command in Tk called [
pack ]. [
pack ] has several supported and documented subcommands that have been the same since Tk 4.0. See
http://www.purl.org/tcl/home/man/tcl8.4/TkCmd/pack.htmlBack in the days of Tk 3, [
pack ] had a different set of subcommands. Those subcommands are no longer part of the official interface of [
pack ], but they do still work. So if you have some ancient script that ran under Tk 3 and used those old subcommands, it's possible that it might still work in a current wish.
No one writing code should use any of those old subcommands of [
pack ] anymore. But someone might notice that [ pack after .w ] actually tries to do something other than return an error, so the old subcommands of [
pack ] are still documented in another man page. That man page can't be called pack.n, so it is called pack-old.n.
