With the introduction of the <literal>.org</literal> directive this one is
less useful (and in most cases, any <literal>.org</literal> statement
you use will actually be at the top of the <literal>.include</literal>d

"""P65-Perl compatibility pragmas
Additional assembler directives to permit assembly of
old P65-Perl sources. This is not, in itself, sufficient,
as the precedence of < and > vs. + and - has changed
between P65-Perl and Ophis.
Supported pragmas are: .ascii (byte), .address (word),
.segment (text), .code (text), and .link."""
