Calling sucros from other sucros
In large sucro applications, many sucros are cooperating. Sucros can
call other sucros in two different ways.
The sucros are either chained or nested. In the former case, one sucro is
followed by another and there is no return to the first one (unless the
second calls the first again). In the latter case, the second sucro is
used as a subroutine and the calling sucro continues again after the
second one has terminated normally.
1 = Chaining of sucros
2 = Nesting of sucros (calling another sucro as a subprogram)
