8 The Parallax Assembler
This chapter describes the Parallax assembler. We have added it for completeness, although we strongly
recommend using the SASM assembler for new projects. You may use the Parallax assembler to re-build
projects that have been developed under a former version of the SX-Key software. You should even
consider changing such code so that is assembles under SASM, or both, because there are only a few
minor modifications necessary for that purpose (see Chapter 9 – Upgrading Existing Code for SASM).
8.1
The general structure of an assembly program for the Parallax assembler is identical to the one
described for SASM in the previous section. Therefore, please refer to Chapter 7.1 – The Structure of an
SX Assembly Program for details.
8.2
The Parallax assembler supports most of the SASM directives as SASM with the exception of GLOBAL,
__FUSE, __FUSEX, FUSES, IRC_CAL, LIST, LOCAL, LPAGE, PROCESSOR, RADIX, RES, SET, SPAC,
STITLE, SUBTITLE, TITLE and ZERO, and different options for the DEVICE directive.
Also, the MACRO and ERROR directives are a subset of those in SASM, i.e. some of the options in
macro definitions are not supported by the Parallax Assembler.
8.2.1
Table 16 – Parallax Assembler DEVICE Options, below, lists the available DEVICE directive options.
