By a script, do you mean a .ssc file in S-PLUS 4.x? Or what? Things which
are run from source() are not committed until the whole input successfully
completes. Submitting from .ssc files appears to work that way (although I
have never seen that written down). On the other hand, running scripts on
Unix by indirection (Splus < infile > outfile) or by Splus BATCH or on
Windows by indirection (Sqpe.exe < infile > outfile) and as far as I know
SPLUS.exe /BATCH all do commit immediately a top-level expression is
finished. They all use much less memory, too.
If none of those appeals, do ensure that the objects you want to save are
assigned, by assign(name, value, w=1, immediate=T) or (whisper it) use <<-.
