| dump * | ( -- ) | Dumps the VM's current status in console |
| swap | ( n1 n2 -- n2 n1) | Swaps the order of the top two items in the stack |
| savestate * | ( n -- ) | Saves the VM's state to file n.fmo |
| words * | ( -- ) | Lists the primitive words loaded to console |
| loadlib | ( n -- ) | Loads the words in n.dll |
| : [;] | Special | Define a user word. The first word following the : in the estack is the name. All words following until ; is the definition of the word |

| if,[else],then | ( n -- ) | If n is true, execute words until else or then. If n is false, execute else to then |
| not | ( n -- n ) | If n is true, push false, if n is false, push true |
| > | ( n1 n2 -- n ) | If n1 > n2, push true else push false |
| < | ( n1 n2 -- n) | If n1 < n2, push true else push false |
| >= | ( n1 n2 -- n ) | If n1 >= n2, push true else push false |
| <= | ( n1 n2 -- n) | If n1 <= n2, push true else push false |
| = | ( n1 n2 -- n ) | If n1 == n2, push true else push false |
| != | ( n1 n2 -- n ) | If n1 != n2, push true else push false (technically pushes "= not" to estack) |
| ! | ( n1 n2 -- ) | Saves n1 to variable n2 |
| @ | ( n -- n ) | Pushes variable n to stack |
