External links modified
[edit]Hello fellow Wikipedians,
I have just modified one external link on ALCOR. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
- Added archive https://web.archive.org/web/20080821024007/http://hopl.murdoch.edu.au/showlanguage.prx?exp=360 to http://hopl.murdoch.edu.au/showlanguage.prx?exp=360
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

ALCOR multiplication sign has nothing to do with runic (or Maltese or other) cross
[edit]The article reads:
- 4. An early "standard" character set for representing ALGOL 60 code on paper and paper tape. This character set included the unusual "᛭" runic cross[1] character for multiplication and the "⏨" Decimal Exponent Symbol[2] for floating point notation.
This is not correct concerning the multiplication sign. The Algol 60 Revised Report uses a multiplication sign (×) that is distinct from the asterisk (*), the latter not being a delimiter of Algol 60. The CCITT-2 code used for paper tapes does not contain either of the two. So ALCOR had to define a code point and chose 110·01¹, thus replacing the question mark (?). None of these characters has anything to do with a runic cross (᛭).
The code point 010·01¹, by the CCITT-2 standard the ENQ control character also named WRU (who are you), was explicitly forbidden in the ALCOR character set. At that time, it was sometimes graphically represented as a Cross pattée (✠) which my have led to the remark about the runic cross which has some similarity. But this was never used as a multiplication sign.
