CONT continues executing the program after the last error. It only keeps 
one copy of where the last error occurred, which gets wiped out by 
errors in interactive mode. You can't CONT an error in interactive mode 
as it only has a single interactive command, which has now been replaced 
with CONT. Hence the error.

It would seem logical to change error handling in interactive mode so 
that the CONT information wasn't overwritten, however there may be 
reasons why it had to work like that.
