+i debased myself and looked it up on google too, and found a few more results.
 maybe i can do something with that because i like `DOES>` and i wanna use it
 
 maybe this sucks shit but my idea is that i compile in a relative jmp with
 `<BUILDS` and fill it in with `DOES>`

+### PNO
+'pictured numeric output'. its forth's numeric output functionality.
+this is me trying to describe it so i can figure it out and implement it.
+note that this forth doesn't have double numbers
+(i don't think it's necessary, since cells are 64 bit)
+so PNO works on single cell values.
+PNO is started by `<#` and ended by `#>`.
