SAIL Changes, New Features
Compiler Version 18, Segment SAISG8

R. Taylor, J. Reiser, R. Smith

October 18, 1974

.starttext
	The new version of SAIL should present relatively few
changes and inconveniences for the user.  There are no known language
incompatibilites.  Unfortunately, it will be necessary to recompile all
 .REL files (including load modules and libraries) for use of the new
SAIL.
	The main reason for bringing up a new SAIL is to accomodate the
new debugger that John Reiser has written.  Thus, the new compiler has
features that allow the compilation to include the semantic information
about the program necessary for the debugger.  A few changes have also
been made to the runtime system to accomodate the debugger, chiefly
the change in the break table features, described below.  The debugger
itself will be available in several weeks.
	A few other changes have been made that the user may see.  These
are described below.
