To set a cell value, the pentimal numbering system is used. In code, the runes themselves are interpreted as commands. Interpreters may choose to provide a convenience output option to convert the runes to raw data, but this is not a provision or requirement of the language. Any modern data encoding can be represented in this way. Arbitrary digital data output is provided if the runes are taken in pairs, to represent hex bytes. There is no option for distinguishing between character and numeric output, which is in keeping with runes which could be used to equally represent words and numbers, depending on context. This allows human readable output in Old Norse. Output therefore is any of the 16 Younger Futhark runes, potentially separated by Null bytes. An actual 0 for arithmetic purposes is achieved by using an unassigned cell, None/ Null, as an operand. 0x0 represents the first rune Fehu, with value 1.

There are 16 runes in the Younger Futhark sequence, these are representable by 4-bit nybbles, 0x0-0xF. Values in RunR are arbitrarily capped at 255, but we do not need the extra, junk characters. ᚱᚢᚾᛅᛦ stays true to its theme by only supporting character output in runes, which should be sufficient for all data output and communication. The author feels that obscure and obfuscated languages which are awkward to write but provide convenient ASCII and numeric outputs are lazy and inelegant. ᚱᚢᚾᛅᛦ makes use of Younger Futhark short-twig runes (all of them), topped up with some Elder Futhark runes to represent less used functions.
