Accessing a field offset

To access a structured type field offset, the Assembler will use following notation:

  <typeName>-><field>

  

where:

• typeName is the name of a structured type.
• field is the name of a field in the structured type associated with the variable. See the following listing for an example of using this notation for accessing an offset.
