I want to resume execution after a divide by 0 exception.
As told by Microware manual I use the F$STrap system call in order to
set up an user trap routine. I managed to get all working but I didn' t
succeed in resuming execution. The manual says: restore all register from
register image pointed by A5 and resume execution 'jumping to the return
program counter'. I don' t understand what is the meaning of 'jumping
to the return program counter'. Any clues? Can any kind soul send me a
do-nothing resuming user trap routine?
     Thanks in advance
