Hmmm... SQL uses <>, doesn't it?
SQL also accepts != and ¬= but both are not language independent. For
example in my German environment I need to specify Ü= instead of != and ^=
instead of ¬=.
That's why this specification should be avoided, like special characters
such as @, (§ instead of @ in the German environment), #, $ should be
avoided in the source code.
May be it would be nice to have syntax alternatives in RPG, that means !=
can be used instead of <>, && and || can be used instead of AND and OR or
even *EQ or *NE can be used instead of = and <>. ... But I think it's not
worth to get implemented.
The main problem I see with these alternatives is these special characters
may not be language independent at least not as long as our source code is
not Unicode!
I don't like to type Ü= if I mean !=,
(I recently had to write a program, where the use/programmer can enter some
snippets/conditions in either RPG, CL or Javascript Style and I had to
translate it into the Javascript).

Hmmm... SQL uses <>, doesn't it? As does BASIC, including Visual
Basic (at least, it did back when I coded in it) as well as CL, right?
At the time that the decision to use <> over != was made, I don't think
anyone realized how popular languages like Java, C# and PHP would make
the != syntax. At the time, there were far more RPG programmers using
languages like VB, SQL and CL than there were RPG programmers using
C/C++. (And Java, PHP, C#, et al didn't yet exist)

I prefer the C style of != personally. Since almost every other language
I've code in it was !=. RPG is the first one I've seen that is<> which
feels very strange when first starting out coming from C/C++ background.
It makes the code less readable for someone not versed in the language,
maybe some people don't care in that case, but I think its nice to play
well with others :)
