  Most BASIC's should have a statement called "RESUME" that allow's
you to re-enter the program at the point that the error occurred.  If
it doesn't, then you're either going to have to use a global variable
to act as a indicator of where you were before the error occurred, or
delve deeper into the mechanics of the BASIC interpreter/compiler.
  Sorry, but I can't see how I can be of more help!
