ADTR AXTR CDFBR CDGBR CDGTR CEFBR CEGBR CFDBR CFEBR CFXBR CGDBR CGDTR CGEBR CGXBR CGXTR CUTFU CUUTF CXFBR CXGBR CXGTR DDTR DXTR FIDBR FIEBR FIXBR LDXBR LEDBR LEXBR LRDR LRER MDTR ME MER MXTR PPNO SDTR SXTR TMH TML I also note that my table has two spurious "extended mnemonic" indications, in that the program to generate it found that mnemonics CONCS and DISCS within OPTABLE(UNI) are marked not to be used during disassembly but they have the same hex opcodes as LBEAR and STBEAR, so it assumes they were extended mnemonics for them. When new instructions were created for the same opcodes, it seemed unnecessary to remove CONCS and DISCS from the UNI table as that could in theory still be useful for reassembling ancient 370 code, but it has caused that weird side-effect. I don't want to update the table manually to fix that, but I may modify the program in future to spot that the opcode is no longer current so it cannot be an extended mnemonic for a current instruction.
