I have thought about a different solution. Reduce menuConvert to a fixed
set of general conversion methods, i.e. one of {NO CONVERSION, LINEAR,
BREAKPOINT, SUBROUTINE}. A separate (new) field of string type could
hold the name of the breakpoint table in case LINR is BREAKPOINT or the
name of a subroutine in case LINR is SUBROUTINE.
