| let arg1 K | assign integer (constant) value K to variable arg1 |
| mov arg1 arg2 | assign one variable to another: arg2 := arg1 |
| add arg1 arg2 arg3 | add one variable to another: arg3 := arg1 + arg2 |
| sub arg1 arg2 arg3 | subtract one variable from another: arg3 := arg1 - arg2 |
| mul arg1 arg2 arg3 | multiply two variables: arg3 := arg1 · arg2 |
| div arg1 arg2 arg3 | divide one variable by another:
arg3 := arg1 /
arg2 More accurately, arg3 is the integer part of arg1 / arg2. If arg2 = 0, exit with error. |
| jmp N | jump to the N-th line of code. Lines of codes are enumerated starting with the 0-th one. |
| cmp arg1 arg2 N< N= N> | conditional jump: compare arg1 and arg2 and jump, depending on the result, to N<-th N=-th, or N>-th line of code. | out arg1 | print value of arg1 | inp arg1 | request an integer value from the user and store it in arg1 |
