J

Does the J solution reject strings with vowels in them? It says on the wikipedia that vowels are never used in the 6-character code, so the function should reject strings that have them. --Mwn3d 04:58, 5 August 2008 (UTC)

The J code isn't a validator, it merely calculates and appends the check digit.

You could modify it to whine about vowels by removing them:

    sn   =.  '0123456789 BCD FGH JKLMN PQRST VWXYZ'  

Not terribly exciting.

R

Does the R solution reject strings with vowels in them? It says on the wikipedia that vowels are never used in the 6-character code, so the function should reject strings that have them. (Is this a common trait of languages with single letter names ;-)

Now it looks like Modula-3 doesn't do the check. Maybe we need to move the algorithm here. --Mwn3d 22:10, 29 September 2009 (UTC)

Well, it seems most of the languages do not check for vowels. Only 8 out of the 26 examples check for vowels. --Mbishop 01:47, 30 September 2009 (UTC)

The specification doesn't say anything about checking for vowels, or validation in general. It says calculate and append the check digit.

'0' checksum

Among the test strings ought to be one that requires a '0' to verify that the checksum is in the range 0..9 instead of 1..10. --IanOsgood 00:34, 7 August 2008 (UTC)

TCL and _

Hi, I generally like the use of '_' in the TCL solution, but on checking, I find that it fails to reject the use of '_' in a SEDOL: <lang tcl>(bin) 11 % set code B0YBKT B0YBKT (bin) 12 % set sedol "${code}[sedol::checksum $code]" B0YBKT7 (bin) 13 % set code B0YBAT B0YBAT (bin) 14 % set sedol "${code}[sedol::checksum $code]" invalid character: A (bin) 15 % set code B0YB_T B0YB_T (bin) 16 % set sedol "${code}[sedol::checksum $code]" B0YB_T7 (bin) 17 % </lang> --Paddy3118 05:01, 28 April 2009 (UTC)

True. I'll fix that. --Glennj 11:19, 28 April 2009 (UTC)
