I don't see this explicitly in the PoOp. Is my recollection correct? That for a "pure clearing" MVCL (source length zero, destination length non-zero) the contents of source address register R2 are not significant, and a specification or access exception on the source address is not possible?
Kacmar (Assembly Language with Assist) gives a specific example for this case. The source addres is set to zero, the source length is set to zero; only the fill character is required. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
