5.4 BASIC Program Execution

5.4.1 Program Execution

Once a BASIC program is stored in memory, it can be executed using one of the two
following procedures.
Using Shift (program area) in CAL mode
EXAMPLE: Shift P9
Executes the program in program area 9.
Entering RUN command in BASIC mode
EXAMPLE: Shift RUN .
Executes the program in the current program area.
Execute the program input in the previous section to determine the volume of a
cylinder with a height ao 10 (radius is fixed at 15).
Shift RUN . .
10 . .

5.4.2 Errors

At times, the results produced by a program are not what is expected. Such irregular
executions can be broadly divided under two major classifications.
