| Code | What do | Structure | ! |
|---|---|---|---|
| mmu | Set MMU locations on disk to jump there for example when you use loop. | mmu (Place on Disk in Hex) | Register 1 = MMU ID Register 2 = Disk Location !Location need by increment by one! |
| gto | Fill Spaces betwaen MMU aplications | gto "Place on Disck in Hex" | |
| jmp | Jump to MMU location. | jmp | Register 3 = Disk Register 1 = MMU ID !Compare need be set on true condition! |
| var | Set Data on Register. | var (Register) "Data" | |
| pri | Print text in terminal. | pri "Text" | |
| nel | Go to next line. | nel | |
| prr | Copy Data from one Register and paste data in another. | prr (Register) (Register) | |
| out | Display Data from Register. | out (Register) | |
| get | Get Data From Input and save in register. | get (Register) | |
| sme | Save data from Register in RAM. | sme (Register) | RAM Location = Register 4 |
| gme | Get Data From RAM and save in Register. | gme (Register) | RAM Location = Register 4 |
| com | Compare two datas. | com | A = Register 1 B = Register 2 OP = Register 3 Avaible Operations: 0 -> > 1 -> = 2 -> < 3 -> <= 4 -> != 5 -> >= 6 -> True 7 -> False |
| alu | Make ALU operations. | alu | OP = Register 0 A = Register 1 B = Register 2 Result = Register 3 |
| wai | Wait for input. | wai | |
| dsc | Go to Disk from Register. | dsc (Register) | You need set Jump before you go to Disck |
| sav | Save data on disck. | sav | Disck = Register 3 Data = Register 2 Location = Register 1 |
| end | End Program | end |

| NULL | 9 | |||
| WAIT | A | Wait for input | ||
| COMPARE | B | Compart A = Register 1 B = Register 2 OP = Register 3 Operations: 0 - > 1 -> = 2 -> < 3 -> <= 4 -> != 5 -> >= 6 -> True 7 -> False | ||
| MMU | C | R1=location R2=content Need by set before jmp location +1 | ||
| Change Disk | D | R | go to dick from register need set location to jmp before | |
| D - > R | E | R | D | Set register |
| STOP | F | end program |
