43[-Q/N$jt$%u)!
Change the first 2, 4 or all nibbles of the Data register with the given value
Dreg=Reg
48[B!

DReg-Cst
48[48'3H!
43'HQ!
43[4303H!
430Q!
Note 1: The Saturn processor is not able to add a constant greater than 16
to a register but if cst is greater than 16, MASD will generate as many
instructions as needed.
Note 2: Even if adding constants to a register is very useful, big constants
should be avoided because this will slow down execution, and generate a
big program.
Note 3: After adding a constant greater than 16, the carry should not be
tested.
Note 4: You can put an expression instead of the constant (MASD must be
able to evaluate the expression strait away). If the expression is negative,
MASD will invert the addition in a subtraction and vice versa.
Note 5: Be careful when using subtraction; it’s easy to be misled. D0-5-6.A
is equivalent to D0+1.A, not D0-11.A
Please read the section on test above for information on what MUST follow a test instruction.
f can NOT be a 7G field.
