ABSTRACT:
Emulation methods are provided for two PACK instructions, one for Unicode data and the other for ASCII coded data in which processing is carried out in a block-by-block fashion as opposed to a byte-by-byte fashion as a way to provide superior performance in the face of the usual challenges facing the execution of emulated data processing machine instructions as opposed to native instructions.
