Line 114:
As for the '''translate''' that you used (above), it removes commas (''','''), quotes ('''"'''), right and left brackets ('''][''') from the values, not just the delimiters. Now, the values shown don't have any of those characters, but still, it's good to program ''as if'' those values had them.
Once those characters are handled correctly, it's one small step to handle blanks and nulls. That's why the REXX versions 1 and 1.5 took extra precautions (more REXX code) to only ''strip'' those characters used as delimiters and not ''translate'' them out of existence. (well, translate them to blanks). Furthermore, the older REXX entries can also handle ''null'' values, which are legal in SETs. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 19:40, 16 December 2013 (UTC)
: Note 1 starts with: " If your code uses lists of items to represent sets ..."
Mine does not!
<br>Please let's end the discussion. My version handles sets that consist of elements not containing blanks (or maybe whitespace) period (The task descripion uses exactly such elements.) Prove the opposite or delete the invalid tag --[[User:Walterpachl|Walterpachl]] ([[User talk:Walterpachl|talk]]) 20:09, 16 December 2013 (UTC)
