    All instructions that have thread-specific filenames or names encoded in it should overwrite this method in order to update (1) the in-memory instruction and (2) the instruction string
    
    Parameters:
    
    pattern - ?
    
    replace - ?
  - preprocessInstruction
```
public Instruction preprocessInstruction(ExecutionContext ec)
```
    This method should be used for any setup before executing this instruction. Overwriting methods should first call the super method and subsequently do their custom setup.
    
    Parameters:
    
    ec - execution context
    
    Returns:
    
    instruction
  - processInstruction
```
public abstract void processInstruction(ExecutionContext ec)
```
    This method should be used to execute the instruction.
    
    Parameters:
    
    ec - execution context
  - postprocessInstruction
```
public void postprocessInstruction(ExecutionContext ec)
```
    This method should be used for any tear down after executing this instruction. Overwriting methods should first do their custom tear down and subsequently call the super method.
    
    Parameters:
    
    ec - execution context
