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.
