Load the Accumulator
Load a value from memory to the accumulator.
32-bit counter: MSW at the high (Even) address.
Float: Loads the integer part only (0-65535)
Load an immediate value to the accumulator
Argument
Memory Register to load from
LOAD The actual value to load to accumulator

Invert and Load to accumulator
Discrete: ON gives “0”; OFF gives “1”.
Other types: bitwise invert e.g. 0xFACE gives 0x0531
{ Calculate Memory Register to
Load from within the { }. The accumulator value is loaded from the location that has been calculated when the “}” statement is reached.
Store the accumulator to memory
Save value from the accumulator to memory
Invert accumulator and save. When storing to a bit Register, a non-zero value is stored as off, and zero is stored as on.
{ Calculate Memory Register to
Store to within the following instructions { }. The current accumulator value is saved to the location that has been calculated when the “}” statement is reached.
{ Calculate the Second Argument of a statement
Use this feature when you need multiple steps to calculate the second argument of a statement.
{ Check the “{“ Column to begin calculation of the argument to a statement. This works for LOAD, STOR and for all of the Logic and Math operations, as well as for the Test/Comparison operations.
Complete and execute a delayed Calculation. This matches the opening brace flag “{“ in the LOAD, STORE, Arithmetic, Logical, and Comparison commands.
It completes the calculation of the argument value and executes the original command.

Set memory register to “1” if accumulator is non-zero. Unchanged if accumulator is zero.
Set memory register to “1” if accumulator is zero.
Clear memory register if accumulator is non-zero.
Unchanged if accumulator is zero.
Clear memory register if accumulator is zero.
Bitwise Logical and Arithmetic operations
Perform Logical / Arithmetic operation between Accumulator and memory.
Result is saved in the accumulator.
AND, OR, XOR – Bitwise Operation
ADD – 16-bit addition with overflow
SUB – 16-Bit subtraction with overflow
MUL – Multiplication (mod 65536)
DIV – Division (x / 0 = 0)
Perform Logical / Arithmetic operation between Accumulator and Immediate value
Negate the argument (Bitwise invert) before performing the operation.
{ Perform Logical / Arithmetic operation between Accumulator and the result of the following calculation within the { }
Compare two values
Memory location to set
Memory location to set
Memory location to clear
Memory location to clear
Register index of the value to use for the second operand
Immediate value to use for the second operand
Applies to Register, Immediate and delayed calculation.
Initial memory location or immediate value (I) for calculation of second operand.

LT – Less Than
Perform Comparison operation between Accumulator and Immediate value.
Accumulatorgets “1” if comparison true. “0” if false.

Call a subroutine forward or backward from the current location, offset from current location
Conditional Call if accumulator is non-zero. (otherwise continue to next line)
Conditional Call if accumulator is zero
Conditional Call a subroutine forward or backward from the current location, offset from current location
Return from subroutine. Returns to the instruction following the last executed
CALL instruction.
Return to calling address if accumulator is non-zero
Return to calling address if accumulator is zero
