:How's it now? The distinction I'm trying to get across is that some operators <em>MIGHT</em> give you string comparison semantics (or some other semantics), while other operators <em>MUST</em> give you string comparison semantics (or fail). It's an important distinction in some languages, or at least in Perl 6. <tt>:-)</tt> But even for languages that only give you polymorphic operators (Python) or coercive operators (Perl 5--at least in the absence of overloading), it's still an important semantic difference. --[[User:TimToady|TimToady]] 00:41, 24 February 2013 (UTC)
:if a string operator operates on a non-string it can:
:# Complain about it.
:# Or if the non-string has an agreed string representation it can convert the non-string then work on the string result.
:Some languages do the former, some the latter. (It's also complicated by some languages having only generic comparison operators, i.e. comparing numbers and strings use the exact same operator). --[[User:Paddy3118|Paddy3118]] 10:56, 24 February 2013 (UTC)

Right, I'm not sure off the top of my head. It has probably been caused by me because the data that I provide usually comes from my own documentation development wiki that requires the addition of the exclamation mark to suppress the wiki engine from interpreting the following backslash symbol, and I have reformatted the page to a new layout at some point and forgot to remove the exclamation marks that I have previously added. If you know for sure the exclamation marks are wrong then remove them. I have got a manual somewhere, but I can't find it at the moment. Cheers, Mark.

No biggie; but it's a shame that you chose to use "<tt>!=</tt>" instead of "<tt>\=</tt>" as the '''NOT EQUAL''' operator. It's only that choice that stopped the program compiling directly to [[NetRexx]] too. That would have made this one of the few program examples in the [[REXX]] family to cross all dialects.
