Aha !!
There is another SCore checkpoint limitation undocummented. Any
sequential program, I mean any program which is not linked with SCore
libraries, are NOT checkpointable.
My feeling is that a sequential program running on SCore is SPECIAL
and the system command is the only way to execute sequential program
in a SPECIAL way.
I am sorry for this inconvenience, but I can not avoid this.
