9.31.6 Local Labels

Local labels may be defined in two ways:

• $N, where N is a decimal number between 0 and 9
• LABEL?, where LABEL is any legal symbol name.

Local labels thus defined may be redefined or automatically generated. The scope of a local label is based on when it may be undefined or reset. This happens when one of the following situations is encountered:

• .newblock directive see .newblock
• The current section is changed (.sect, .text, or .data)
• Entering or leaving an included file
• The macro scope where the label was defined is exited
