Up: SIC Language Internal Help
EXIT always ends SIC execution, at any level. In interactive sessions,
<^D> has the same behaviour as EXIT.
On the opposite <^Z> only ends the current level of execution, so that
when typed at the top level, <^Z> also ends the session. Note that <^Z>
may be trapped when interactive editing is enabled.
Note that end of SIC execution does not necessarily means end of program
execution: SIC may be entered again later by the calling program.
