public String getInstructions(String[] inputs,
                              String output)
```
    Generate the complete instruction string for this Lop. This instruction string can have a variable number of input operands. It displays the following:
    
    Execution type (CP, SPARK, etc.)
    Operand delimiter (°)
    Opcode (printf, etc.)
    Operand delimiter (°)
    Variable number of inputs, each followed by an operand delimiter (°)
    
    Input consists of (label · data type · value type · is literal)
    
    Output consisting of (label · data type · value type)
    Example:
    The following DML
    print('hello %s', 'world')
    generates the instruction string:
    CP°printf°hello %s·SCALAR·STRING·true°world·SCALAR·STRING·true°_Var1·SCALAR·STRING
