Computation of Two Consecutive Program Blocks for SCMPDS

Summary.
-
In this article, a program block without halting instructions
is called No-StopCode program block. If a program consists of two blocks,
where the first block is parahalting (i.e. halt for all states) and
No-StopCode, and the second block is parahalting and shiftable,
it can be computed by combining the computation results of the two blocks.
For a program which consists of a instruction and a block, we obtain
a similar conclusion. For a large amount of programs, the computation
method given in the article is useful, but it is not suitable to recursive
programs.
