- Name and parameters of a instruction can be edited via context menu (right click on block).
- Parameters work as local variables and can be used inside the custom instruction.
- Custom instruction can be terminated at any point using return block.
- Instruction call
- Executes the custom instruction, with defined parameters.
- Can be placed in any sequence as any other instruction.
- Any Instruction which returns a value is called expression.
- Expression definition work in same way as for statement instructions.
- Instruction call has to be docked as input of another instruction as it would be a variable or literal.
