Section 48
A SECTION pseudo-instruction written in the last section of the page not only clears the step counter
but also updates the page counter, so a new page need not be specified.
A label can be written before the SECTION pseudo-instruction, but it cannot be referenced because it is
not cataloged in the label table.  In this case, write the label in the statement following the SECTION
pseudo-instruction.
