as: Symbol Attributes

 
 5.5 Symbol Attributes
 =====================
 
 Every symbol has, as well as its name, the attributes "Value" and
 "Type".  Depending on output format, symbols can also have auxiliary
 attributes.
 
    If you use a symbol without defining it, 'as' assumes zero for all
 these attributes, and probably won't warn you.  This makes the symbol an
 externally defined symbol, which is generally what you would want.
