Word marked with "*" are primarily for testing purposes for sim owners and not end users.
| Word | Stack | Description |
|---|---|---|
| dup | ( n -- n n ) | Duplicates the top item of the stack |
| . * | ( n -- ) | Prints the top item of the stack in console |
| 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 |
| savestack | ( ... n -- ) | Pops the entire stack into variable n |
| loadstack | ( n -- ... ) | Push's the stack saved in variable n |
| clearstack | ( ... -- ) | Clears the entire stack |
| 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 |

| Word | Stack | Description |
|---|---|---|
| + | ( n1 n2 -- n ) | Adds n1 and n2 together. If n1 or n2 are strings, result will be a combined string |
| - | ( n1 n2 -- n) | Pushes n1 - n2 |
| * | ( n1 n2 -- n) | Pushes n1 * n2 |
| / | ( n1 n2 -- n ) | Pushes n1 / n2 |
| round | ( n -- n ) | Rounds n to nearest integer |
| sin | ( n -- n ) | Pushes the sin of n |
| cos | ( n -- n ) | Pushes the cos of n |
| tan | ( n -- n ) | Pushes the tan of n |
| pi | ( -- n ) | Pushes PI |
| abs | ( n -- n ) | Pushes the absolute value of n |
| sqrt | ( n -- n) | Pushes the square root of n |
| pow | ( n1 n2 -- n) | Pushes n1 to the n2'th power |
| floor | ( n -- n ) | Floors n and pushes it |
| vecmag | ( x y z -- n) | Pushes the vecmag of vector <x, y, z> |
| vecnorm | ( x y z -- x y z ) | Pushes the normalized vector for <x, y, z> |
| vecdist | ( x1 y1 z1 x2 y2 z2 -- n ) | Pushes the distance between <x1, y1, z1> and <x2, y2, z2> |
