AnnoAllOff

Opens a DCL picker to choose Model/Layout tabs, then sets ANNOALLVISIBLE to 0 on the selected tabs.
Provides quick selection controls for All or None before applying the change.

Builds a temporary DCL dialog at runtime that lists all tabs (including Model) and allows multi-selection.
After the user confirms the selection, the routine switches to each chosen tab and runs the command ANNOALLVISIBLE with value 0.
Stores and restores key environment state such as CTAB, TILEMODE, and MSPACE so the user returns to the prior context after execution.
Note: the variable ANNOALLVISIBLE is maintained per Model tab and per Layout tab, so this routine applies changes per tab rather than per viewport entity.

AAOFF:WriteDcl writes the DCL definition to a temporary .dcl file used to display the selection dialog.
AAOFF:GetTabNames enumerates the document layouts via ActiveX and returns a list of tab names including Model.
AAOFF:MakeAllIndexString generates the space-separated index string required by a multi-select list box to select all items.
AAOFF:IdxList->Names converts the list box index string into the corresponding tab name list for processing.
AAOFF:SetAnnoAllVisible0 iterates selected tabs, forces paperspace on layouts, executes ANNOALLVISIBLE to set it to 0, then restores the previous tab and mode settings.
c:AAOFF orchestrates the workflow: builds the tab list, shows the dialog, handles All/None actions, applies the setting, and cleans up temporary files.

• Runtime DCL generation creates a dialog file in a temp location and loads it for the session.
• Multi-select tab picker allows choosing any combination of Model and Layout tabs for updating.
• All button selects every tab in the list box using a generated index string.
• None button clears the selection to prevent changes from being applied.
• Per-tab update switches CTAB for each chosen tab and sets ANNOALLVISIBLE to 0.
• Layout handling forces paperspace on layout tabs by setting MSPACE false when TILEMODE indicates a layout context.
• State restoration restores prior CTAB, TILEMODE, and MSPACE values after processing.

If the user confirms a selection, ANNOALLVISIBLE becomes 0 on each selected tab and the prior tab/mode state is restored afterward.
If no tabs are selected, prints AAOFF: Nothing selected. No changes made.
If the dialog is cancelled, prints AAOFF: Cancelled.
If the dialog cannot be loaded, prints AAOFF: Could not load dialog.
Always deletes the temporary DCL file and unloads the dialog definition at the end of the routine.
