D - Destination device.
S - Source device.
m, n- Number of active devices, bits or an operational constant.
Additional numeric suffixes will be attached if there are more than one operand with the same
function e.g. D

1

, S

3 

or for lists/tabled devices D

3+0, 

S

+9 

etc.

MSB - Most Significant Bit, sometimes used to indicate the mathematical sign of a number, i.e.
positive = 0, and negative = 1.
LSB - Least Significant Bit.

 

- 

An instruction operating in 16 bit mode, where 

 identifies the instruction

mnemonic.

P -  A 16 bit mode instruction modified to use pulse (single) operation.

D

 

-  An instruction modified to operate in 32 bit operation.

D

P -  A 32 bit mode instruction modified to use pulse (single) operation.

- A repetitive instruction which will change the destination value on every scan unless

modified by the pulse function.

- An operand which cannot be indexed, i.e. The addition of V or Z is either invalid or will

have no effect to the value of the operand.
