In this process, the mnemonic codice_25, for "LOAD", was replaced by various abbreviations of the words "LOAD", "STORE" and "MOVE", intermixed with other symbolic letters. The mnemonic letter codice_26, for "memory" (referenced by HL), was lifted out from within the instruction mnemonic to become a syntactically freestanding "operand", while registers and combinations of registers became very inconsistently denoted; either by abbreviated operands (MVI D, LXI H and so on), within the instruction mnemonic itself (LDA, LHLD and so on), or both at the same time (LDAX B, STAX D and so on).
