| *("var1",var2) | var1*=var2 | |
| print(var) | pt(var) | Prints text. No quotemarks needed for variables, but needed for strings. |
| concat("var1",var2) | ct("var1",var2) | Concats two strings |

| die() | exits program | |
| drawrect(x,y,w,h) | dw(x,y,w,h) | draw rectangular |

| drawline(x,y,x1,y1) | dl(x,y,x1,y1) | draw line |
| repeat(x); ... endcycle(); | repeats x times | |

| sleep(val) | sleeps for val milliseconds | |
| fillscreen(r,g,b) | fills entire window with color | |
| cls() | clears screen and graphics buffer | |
| goto(val) | sends interpreter to val expression(!) not the code line, so it's recommended to use newlines properly | |
| loadpic("picID","filename.png") | loads image to memory | |
| loadpic("picID","filename.png") | loads image to memory | |
| drawpic("picID",x,y) | draws image by id | |
| drawoval/filloval(x,y,w,h) | draws or fills oval | |
