Any SaveCursor() call you make and don't reverse yourself will be
reversed when your script or function exits. Put another way, if you
call SaveCursor() in a script or function, the cursor is saved only until that
script or function exits, or until you call RestoreCursor(), whichever
comes first. Think of SaveCursor() as putting something on the script
or function's stack, along with its local variables. When the script
or function exits, its stacked is cleaned up.

Hi Raymond,
Try this bit of logic.
This assumes the PC cursor is on when you start your script.
Note that when you save and restore cursors, you have to restore them in
reverse order. Also, I forget which functions automatically restore cursors, so
I always restore them myself.
Below is untested code.
SaveCursor() ; Saves the location of the PC cursor
InvisibleCursor()
SaveCursor() ; Save invisible cursor location
RoutInvisibleToPC()
PriorWord()
NextCharacter()
let found = FindString(sString, s_Prior) ; try to put invisible cursor there.
if found then ; The invisible cursor is in the right place.
RoutPCToInvisible() ; Put the PC cursor there.
PcCursor() ; Activate PC Cursor.
RestoreCursor() ; Pop the PC Cursor location off the stack.
else
RestoreCursor() ; Put the PC cursor where it was
EndIf
RestoreCursor() ; Put the invisible cursor back where it was

Hi Tony,
I can't use the SaveCursor/RestoreCursor functions because the FindString
with s_next and the one with s_prior are attached to a key. And pressing
this key should bring you each time to the next or prior occurrence.
Cheers,
Raymond
