    Parameters:
    
    Owner - Calculator which will call this Opcode
- Method Detail
  - Backup_Display
```
private void Backup_Display()
```
    Backup the display (A and L Register). This is necessary as I/O operations might be followed by file name or file number which will is composed in the A_Text and L_X register respectively. To change this a massive change Op_Alpha or Op_Num would be needed. A backup is a lot simpler.
