Instruction are written in the format operation arg1 arg2, with each instruction on a separate line. Operations may be upper or lower case.
| Operation | arg1 | arg2 | Explanation |
|---|---|---|---|
| acc | Storage / Number | - | Add Number (or Number in Storage) (may be negative) to accumulator. |
| Jumps | |||
| jmp | Number/Label | - | Jump to Number/Label |
| jre | Number | - | Jump Number instructions (relative). |
| jtr | Number/Label | - | Absolute jump to Number/Label only when status is true. |
| bra | Number/Label | - | Branch to subroutine at Number/Label. Instruction pointer is pushed to the stack. |
| brc | Number/Label | - | Branch to subroutine at Number/Label only when status is true. Instruction pointer is pushed to the stack. |
| ret | - | - | Return from subroutine. Pop instruction pointer from stack. |
| Comparisons | |||
| grt | Storage | Storage / Number | If value in Storage is greater than value of second argument, set status to true |
| geq | Storage | Storage / Number | If value in Storage is greater or equal to value of second argument, set status to true |
| equ | Storage | Storage / Number | If value in Storage is equal to value of second argument, set status to true |
| leq | Storage | Storage / Number | If value in Storage is less or equal to value of second argument, set status to true |
| les | Storage | Storage / Number | If value in Storage is less than value of second argument, set status to true |
| neq | Storage | Storage / Number | If value in Storage is not equal to value of second argument, set status to true |
| Working with registers | |||
| add | Storage | Storage / Number | Add value in Storage / Number to Number, write result into data register r0 |
| sub | Storage | Storage / Number | Subtract Storage / Number from value in Storage, write result into data register r0 |
| mul | Storage | Storage / Number | Multiply Storage / Number with value in Storage, write result into data register r0 |
| neg | Storage / Number | - | Negate value in Storage or Number, write result into data register r0 |
| mod | Storage | Storage / Number | Calculate modulus of value in Storage with value in Storage or Number, write result into data register r0 |
| cei | Storage / Number | - | Round Storage / Number to the next highest integer, write result into data register r0 |
| flo | Storage / Number | - | Round Storage / Number to the next lowest integer, write result into data register r0 |
| div | Storage | Storage / Number | Divide Storage / Number with value in Storage, write result into data register r0 |
| mov | Storage1 / Number | Storage2 | Copy value from Storage1 or Number to Storage2 |
| swp | Storage1 | Storage2 | Copy value from Storage1 to Storage2 and value from Storage2 to Storage1 |
| I/O | |||
| inp | Storage | Read one value from input and store it at storage. Will block execution until an input is ready. | |
| out | Storage / Number | - | Output value of Number or at Storage to out. |
| Stack operations | |||
| pus | Storage / Number | - | Push Number or value in Storage to stack |
| pop | Storage | - | Remove the top most value from stack and place it in Storage. |
| top | Storage | - | Copy the top most value from stack and place it in Storage. |
| Control operations | |||
| nop | - | - | Do nothing |
| rnr | Number | Number | Set range of random number generator (rnd). |
| rst | - | - | Reset accumulator and data register to 0, reset status to false |
| end | Storage / Number | - | Stop machine gracefully with return value |
