They must start with a letter, dot, or +underscore.</P +><P +>LWASM also supports the concept of a local symbol. A local symbol is one +which contains either a "?" or a "@", which can appear anywhere in the symbol. +The scope of a local symbol is determined by a number of factors. First, +each included file gets its own local symbol scope. A blank line will also +be considered a local scope barrier. Macros each have their own local symbol +scope as well (which has a side effect that you cannot use a local symbol +as an argument to a macro). There are other factors as well. In general, +a local symbol is restricted to the block of code it is defined within.</P +><P +>By default, unless assembling to the os9 target, a "$" in the symbol will +also make it local. This can be controlled by the "dollarlocal" and +"nodollarlocal" pragmas. In the absence of a pragma to the contrary, for +the os9 target, a "$" in the symbol will not make it considered local while +for all other targets it will.</P +></DIV +><DIV +CLASS="NAVFOOTER" +><HR +ALIGN="LEFT" +WIDTH="100%"><TABLE +SUMMARY="Footer navigation table" +WIDTH="100%" +BORDER="0" +CELLPADDING="0" +CELLSPACING="0" +><TR +><TD +WIDTH="33%" +ALIGN="left" +VALIGN="top" +><A +HREF="x168.html" +ACCESSKEY="P" +>Prev</A +></TD +><TD +WIDTH="34%" +ALIGN="center" +VALIGN="top" +><A +HREF="index.html" +ACCESSKEY="H" +>Home</A +></TD +><TD +WIDTH="33%" +ALIGN="right" +VALIGN="top" +><A +HREF="x183.html" +ACCESSKEY="N" +>Next</A +></TD +></TR +><TR +><TD +WIDTH="33%" +ALIGN="left" +VALIGN="top" +>Source Format</TD +><TD +WIDTH="34%" +ALIGN="center" +VALIGN="top" +><A +HREF="c43.html" +ACCESSKEY="U" +>Up</A +></TD +><TD +WIDTH="33%" +ALIGN="right" +VALIGN="top" +>Numbers and Expressions</TD +></TR +></TABLE +></DIV +></BODY +></HTML +> \ No newline at end of file
