I'm not sure what you're trying to say. Length is either a nybble or an 8-bit byte, depending on the instruction, but in any event EX executes a copy of the target with a logical or on bits 8-15 of the target: FA is reporting the in-storage contents of bits 8-15 and using that unmodified contents to determine how much of the target's operand to print.
In this case, R2 contains XL4'D0', the EX target contains X'F005xxxxxxxx' and the report contains only one byte of the target. -- Shmuel (Seymour J.)
