Studying the flowchart, we see that this program
could be split into three smaller programs, or
LINKS:
PGMAB, which is made up of blocks A and B
PGMX, which was block
X
MAIN, which is the main program
Executing with no LOCALs, we find that the program
MAIN requires SOCAL level 2 to fit into core, and
that it runs no faster than before.
