VARIABLE - Declare Symbol Variable

VARIABLE - Declare Symbol Variable

Syntax

variable <label>[=<expr>][,<label>[=<expr>]...]

Description

Creates symbols for use in MPASM assembler expressions. Variables and constants may be used interchangeably in expressions.

The variable directive creates a symbol that is functionally equivalent to those created by the set directive. The difference is that the variable directive does not require that symbols be initialized when they are declared.

The variable values cannot be updated within an operand. You must place variable assignments, increments, and decrements on separate lines.

Example

Please refer to the example given for the constant directive.
