- Hi all,
-
- Does anybody know how to tell from within a programme (preferably sys_RPL
- but user_RPL will suffice for a start) what menu is currently being
- displayed?
-
- ie: is there an object that can be accessed which tells me whether, say, the
- MTH or the CST or the PRG menu is currently displayed?
-
- Second question: Are the built-in menu grobs held anywhere as one-line
- grobs and are they accessible? ie: is page 2 of the MTH menu for instance
- a 131 X 9 GROB held somewhere that can be recalled to the stack?
-
- Third question: Same as second question but regarding user menus, such
- as variables lists and directories menu grobs. Obviously these would be in
- RAM rather than ROM (where the built-in menus would be) - are they
- stored as menu grobs individually or page-by-page grobs which
- are altered when the user creates a new variable/directory or ORDERs them?
-
- Surely these menu grobs are not generated each time they are displayed?
- Or is the memory overhead of storing the grobs too much to pay for speed?
-
- Anyone?
- Conan.
