Outside the critical region, a continuous run is desired. Inside the critical region, there is a single
instruction step. The operator must press the carriage return or space bar on the terminal
keyboard after each statement executed.
Example 2: The trace region is set from 0 to 2000
16 ,
with the trace format index number equal
to 3. (Trace type 3 defaults to a full trace.) The snapshot prints workspace registers I through 4
and memory locations 1000
16
to 1004
16 ,
A breakpoint is set at 0474
16
with snapshot 1
associated. A Modify Registers (MR) command sets the program 'counter to 046C
16 ,
and
execution is begun by issuing an Execute User Program under SIE or Trace (RU) command .
