LABEL Assembler Statement

Arguments

symbol 〚:〛 LABEL 〚type〛

Description

The LABEL statement defines a symbol name for a location in a section. The defined label inherits the attributes of the parent section. It may not be defined outside a section. Label definitions may optionally include a type which specifies the type of access required by the assembler. If no type is specified, the label type is set based on the section (NEAR for Code Sections, BYTE for Data Sections, and BIT for Bit Sections).

type	Description
NEAR	The label receives the NEAR type which implies that it must be defined in a Code Section.
FAR	The label receives the FAR type which implies that it must be defined in a Code Section.
BYTE	The label receives the BYTE type which implies that it must be defined in a Code or Data Section.
WORD	The label receives the BYTE type which implies that it must be defined in a Code or Data Section and must start at an even (word) address.
BIT	The label receives the BYT type which implies that it must be defined in a Bit Section.

The assembler checks access types for mismatches and generates an error if a problem occurs.
