Symbols

A symbol is a group of characters that represents a value, such as an address, numeric constant, string constant, or character constant. There is no length limit to symbols.

The syntax of a symbol is:

  symbol ::= label | equate 

In general, symbols have file-wide scope. This means:

• You can access the symbol from anywhere in the file that includes the symbol definition.
• You cannot access the symbol from another file.

However, it is possible for symbols to have a different scope, as the Local Labels subsection explains.

• Labels
  
  
• Equates
  
  
• Case-Sensitive Identifiers
