BIT FIELDS
Bit fields are values in memory that are not aligned to byte boundaries Examples are PACKED arrays and records used in
Pascal ‘‘Extract’’ instructions read and align a bit field ‘‘Insert’’ instructions write a bit field from an aligned source

Options on all string instructions are
B (Backward)
U (Until match)
W (While match)
All string instructions end when R0 decrements to zero
Decrement string pointers after each
step rather than incrementing
End instruction if String 1 entry matches
R4
End instruction if String 1 entry does not
match R4
