I remember back in college I loved the idea of a "readable" language. One
where you wouldn't need !=, ||, && and the like. You could just say
things like NOT, EQUAL, AND, XOR, etc. There are some languages that
implement many of these common ones now days. SQL seems to be the closest
that I've seen actually, and that is only a query language.
I hadn't remembered the <> from when I did pascal in 10th grade. And back
when I coded in VB6 I would code if (a not = b) because I found it more
readable than <>. Of course I had forgotten these things until this
thread. What a jog down memory lane, and my memory lane is shorter than
most on this list :-)

AW: More on RPG style
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).
Mit freundlichen Grüßen / Best regards

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'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 :)
