Define a Types of labels: redefinable named values
Types of labels: Redefinable named valuesredefinable named value:
<name>[:][:] Pseudo instructions: defl, set and '='
Labels: SETset <value>
<name>[:][:] defl <value>
<name>[:][:] = <value>
Pseudo instructions: Label definition
Numeric expressions: Labels
8080 Assembler: LabelsLabels defined with this keyword can be redefined at some later position.
Especially for use in Pseudo instructions: macro, .macro, endm and .endm
8080 pseudo instructions: MACROmacros it is useful to allow Pseudo instructions: Label definition
