I'm not claiming the behavior described here are bugs, but rather misfeatures as they really don't break anything. --- Press VAR Press LIBRARY Press MEMORY Press LAST MENU; notice you end up in the VAR menu, not the LIBRARY menu as one might expect. --- Store a library in port 0. Attach it to the current directory. Put the library ID (:port:lib) on the stack, DUP it. Press MEMORY, enter { DETACH }, press PRG OBJ OBJ-> DROP. On the stack you will have the ID twice and the command DETACH on level 1. Go to the LIBRARY menu, then to the library just attached. Press EVAL. This will DETACH the library. No change in the menu. Press PURGE. This will remove the library from the port. No change in the menu. Press on of the menu keys, you get an "Undefined XLIB name" error. One would expect the menu to blank out when the library is detached. The LIBRARY menu is appropriately updated. --- I haven't seen these two misfeatures described on the net previously - apologies if I'm beating a dead horse. I have a rev D, I wonder if this is changed in rev E. -- Jan Brittenson bson@ai.mit.edu

Owner's Manual, page 57: "Pressing [right-shift] LAST MENU (found over the 3 key) returns you to that menu. Menus of menus (such as the MTH menu) aren't stored as the last menu.

When you press LIBRARY, the menu is created and stored as a temporary menu. This remains the menu until something causes it to be updated, such as pressing LIBRARY again. Similar effects can be seen by doing certain things with the Solver or TMENU. -- edp (Eric Postpischil) "Always mount a scratch monkey." edp@jareth.enet.dec.com

This SHOULD be expected. LAST MENU never retrieves the menus that consist of only submenus, viz. MTH (menu 3), PRG (menu 10), LIBRARY (menu 24), and UNITS (menu 42). This is described in the manual, btw. They went to special effort to add this feature. Good thing, too. It lets you flipflop between, say, the UNITS TEMP menu and the EQ UTILS (library 268) menu with one keystroke (LAST MENU). Couldn't otherwise, except by using the MENU command, which would detour the user- friendliness of the LAST MENU key. -- Joseph K. Horn -- Peripheral Vision, Ltd. --
