Global$ test1
Define$ test2$

Procedure Test()
  Protected$ test3$
  Static$ test4$
EndProcedure

The keywords "Global", "Define" and "Protected" support the suffix "$", but "Static" not.

I think it should be possible, so that it is consistent.

Edit:
Or remove the suffix "$" for all keywords.
For keywords, the suffix has no advantage over ".s", as it is the case on variables.

What is the meaning of $ after Global, Define, ...
I can't find a documentation entry for this.

I think these are some relics from Pb starting time. This is also available with Procedure$.

There are several stupid things (sorry Fred) like '=<' or '=>' that don't make a code any better and should be removed.

"$" = ".s"

The suffix "$" works also on many other keywords -- Read$/Data$ (DataSection), Procedure$, etc. --, not only on variables.

How would you propose to do "less than or equal to" then?

PureBasic is Basic, and "=<" is standard Basic.

As you wrote, it means "less than or equal." It is not called "equal or less than". In Basic dialects like VB6, VBA, QBasic '<=' is used. Even if it works the other way around, it doesn't make sense and doesn't make a code any better.

Surely you jest?

Sorry, this is not exactly correct.

The suffix ".s" is only needed for the declaration. Otherwise, it can be appended to a variable name, but there is no need to do so.
In contrast, the suffix "$" is part of the variable name. If a string is declared with suffix "$", then that suffix has to be appended always to the variable name:

Code: Select all

; PB 5.70 LTS

Define foo.s
Define bar$

foo.s = "Hello"   ; allowed
foo   = "Hello"   ; allowed
bar$  = "world"   ; allowed
; bar = "world"   ; not allowed, because 'bar' is an integer variable

My suggestion for removing that inconsistency is, not to allow "Global$", "Define$", "Protected$" and "Procedure$" anymore, because that doesn't make sense IMHO.

Relational operators in almost all conventions tend to place the non-equal comparative before the equal one (ie: <= >= !=).

However, PureBasic is hardly a conventional programming language. While the flipped syntax is convenient, better to stick to mainstream conventions; in case it's enforced in future versions.

The string symbol ($) goes back to the early days of BASIC, where most string functions were suffixed with it (eg: STR$, LTRIM$, UCASE$, MKI$, etc.).

Nice to maintain some pure BASIC legacy.

Yes. And as you know, PureBasic does not follow that tradition, since those functions are named STR, LTRIM, UCASE etc. in PureBasic.

In the case of using it as a suffix on the keywords, it is correct and this was the question.
But thank you for clarifying the different meaning of the suffix for variables.

Yes, that's why I like "$" more than ".s" on string variables. So it is always clear which variables are for numbers and which are for strings, without having to think up a prefix/suffix yourself.

I think the suffix on "Procedure", "Data" and "Read" is ok, but can also be removed, because it has no advantage over ".s".
For the other keywords, I don't use the suffix:

Code: Select all

Global$ variable$

Nonsense in my case, because I always use the suffix on string variables.
That's enough:

Code: Select all

Global variable$

Ooops. I mixed that up, sorry! You are right, of course.

Well ... using them as suffix for those keywords, "$" and ".s" have the same effect.
But using them as suffix for variable names, "$" and ".s" do not have the same effect.

Another inconsistency ... One more reason IMHO for removing support for Define$, Global$ etc. from the language.

Global$ etc. occupies useless variable names. Even if these identifiers can be used in the code, it simply looks unattractive and confusing at a quick look at the code.

Structure MyStruc
  aaa.i
  bbb.i
  Global$
  ccc.i
EndStructure

or..

Code: Select all

Global$ Global$ = "abc"

I think in the EU it should be

Code: Select all

Global€ Global€ = "abc"
