From fb836cb4cae07b2c66a41ad1413a8cab1a080e6a Mon Sep 17 00:00:00 2001 From: Miquel Sabaté Solà Date: Tue, 14 Jan 2025 21:07:07 +0100 Subject: Implement the .res control statement MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Similarly to other assemblers, this allows the programmer to write a definite amount of bytes with the same values. Compared to other assemblers there are two things to notice. First, there is a limit to it (i.e. whatever can fit in 2 bytes). Second, if the fill value is not provided, then it will default to the current mapping's fill value, or just 0x00 if the current mapping doesn't define one of its own.
