defWORD Directive

The defWORD directive directs SPLat/PC to assign a value to a label and reserve a nominated amount of RAM to hold the data associated with that label. It is part of the Automatic RAM Allocation scheme introduced in SPLat/PC V7.15.2 (May2005).

Syntax:

Label     defWORD      {Value}

Label is any properly formed label. Value is an optional numeric constant. If not used Value defaults to 1. Typically you would specify Value if you intend to access an array of data using indexed addressing.

This will automatically allocate 2x Value bytes of RAM and assign the address of the first byte to Label.

An error will be raised if SPLat/PC is unable to find enough free RAM.
