Well, there are, and they all have mnemonics that could easily be confused with halfword instructions... e.g. LFH, AHHHR, AIH.
JCT is not even close to one of them. It sounds like Martin's message was cut-off mid-stream, and I presume he meant to say JCTH (Branch Relative on Count High); which is not to be confused with JXH (Branch Relative on Index High), where "High" means something else. Makes me think some architects were High. :-) sas On Tue, Feb 12, 2019 at 12:06 PM Martin Truebner <[email protected]> wrote: > Gary, > > and there are a few instructions that use straight the upper half of > the 64 ...ie JCT --- > > Martin > -- sas
