Symbols list:
D - Destination device.
S - Source device.
m, n- Number of active devices, bits or an operational constant.

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

Instruction modifications:
-
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.
