80 >Symbols have no length restriction. They may contain letters, numbers, dots,
81 dollar signs, and underscores. They must start with a letter, dot, or
82 underscore.</P
83 ><P
84 >LWASM also supports the concept of a local symbol. A local symbol is one
85 which contains either a "?" or a "@", which can appear anywhere in the symbol.
86 The scope of a local symbol is determined by a number of factors. First,
87 each included file gets its own local symbol scope. A blank line will also
88 be considered a local scope barrier. Macros each have their own local symbol
89 scope as well (which has a side effect that you cannot use a local symbol
90 as an argument to a macro). There are other factors as well. In general,
91 a local symbol is restricted to the block of code it is defined within.</P
92 ><P
93 >By default, unless assembling to the os9 target, a "$" in the symbol will
94 also make it local. This can be controlled by the "dollarlocal" and
95 "nodollarlocal" pragmas. In the absence of a pragma to the contrary, for
96 the os9 target, a "$" in the symbol will not make it considered local while
97 for all other targets it will.</P
