Valid constants for the mask are -32768…32767 (word) and
-2,147,483,648…2,147,483,647 (long word). The mask is displayed
as a hexadecimal unsigned value from 0000 0000…FFFF FFFF.
Addressing Modes and File Types can be used as shown in the following
table:
Updates to Math Status Bits
After a MVM instruction is executed, the arithmetic status bits in the status
file are updated. The arithmetic status bits are in word 0 bits 0-3 in the
processor status file (S2).
