New machine language port

[cahlucas]

Hello all,

I am porting a machine language program written for the HP-48 to the HP50g, and I encounter some problems with this. The mnemonics below are not recognized by MASD. Are there replacement mnemonics for this? This list is not the program itself, but the mnemonics from the program parts, with which I have problems, and are in a random order. Who can help me with this? Sincerely, Karel.
