There are three ready-made runtime systems provided with the
distributions, sprt.exe, sprti.exe, and (only on Windows)
sprtw.exe. These have been created using
$ spld --main=restore '$SP_APP_DIR/main.sav' -o sprt.exe $ spld --main=restore '$SP_APP_DIR/main.sav' -i -o sprti.exe $ spld --main=restore '$SP_APP_DIR/main.sav' --window -o sprtw.exe
These are provided for users who do not have a C-compiler available. Each program launches a runtime system by restoring the saved state main.sav (located in the same folder as the program).
The saved state is created by
save_program/[1,2]. If it was
save_program/2, then the given startup goal is run. Then,
user:runtime_entry(start) is run. The program exits with 0 upon
normal temination and with 1 on failure or exception.
sprti.exe assumes that the standard streams are
connected to a terminal, even if they do not seem to be (useful under
Emacs, for example). On Windows only,
sprtw.exe is a windowed
executable, corresponding to
