Apologies for the repeat posting, but the earlier link to the syntax file was not working. The webserver was not liking sending back .ini files (which is the extension of the syntax file).
I’ve uploaded the syntax file again with the original entry. This time it is a zipped file. You’d need to unzip this into the {PSPad install path}/syntax directory.
Thanks to Ken Auenson for pointing this out.
