Step 3
Reexecuting TECH1 with all eight subroutines as
LOCALs (L, M, N, P,
Q,
X, Y, Z), we learn from
the load map that this strategy not only gets the
program into core storage, but eliminates the need
for SOCALs.
It
runs quite slowly, however, and

takes nearly 60 minutes to go to completion, com-
pared with the 15 minutes we expected. The sound
of the disk arm moving gives us a clue to what is
wrong: we have caused an overlay to be placed
between the disk READ/WRITE commands. In this
case the LOCAL subroutines L, P, and
Q
are the
culprits.
