Bug 4.31 variables ?

Hi,
I believed a global CARD$ was different than a local card$ in a procedure ? Did I ever missed they were the same ? I'm surprised, pretty sure was different, as one is in uppercase, over in lowercase....

PureBasic is not case-sensitive, so CARD$, card$ and cArD$ are all same.

PB is case insensitive.

the Case does not distinguish Names in PureBasic, it never did!
both names are the same, you could even write Card$
if you want a different Var than the Global in a Proc, use
if you need
both Variables, use different names for them, e.g. G_Card$ and L_Card$ (Global and Local)

To be honnest, it did, but a very very long time ago
Code: Select all
27 January 2002 : Version 2.90
- Changed: Variables, Arrays, LinkedList and Constants are now case insensitive.

Im really (really really) cheerfull that you did this step.
There is nearly nothing, which is more annoying me then case-sensitive-bugs. In my opinion it increaes, combined with a good editor, the readability of code (auto correction).

Combined with EnableExplicit I don't think case sensitivity would be a problem.

What orig poster may have been confused about reading previously, is that 'CARD$' is different variable than 'CARD.s'

'D' is a symbol and i don't see there anything to do with the symbol 'd'.
Your brains are very well educated to do a work:
convert 'D' to 'd' or viceversa
Work which is a nonsense, of course, because it could be easely saved.

And and and doesn't mean the same, right? They never did, right? Oh wait, I think they do!
At first they had only uppercase letters. They made the others for readability. The readability increases when upper- and lowercase letters are mixed in the correct way. If they are mixed in an incorrect way decreased readability occurs.

PB editor allows to do "decreased" readability, because it allows things like this:
Code: Select all
varia.f+rition.f
;code...
;code...
;code...
vARiA.F-rItiON
or
But Co is cobalt
while CO is carbon monoxide

IMHO, it's better than having several identifiers which holds differents values with the 'same' name.
Code: Select all
sum = 10
Sum = 20
SuM = 30
SUM = 40
Debug Sum

This will probably turn into another war of the cases.
I'm with Fred.
And it's probably time to lock this one too
cheers

you only have to suffer from dyslexia to know that languages like C are a pain in the butt when it comes to finding a bug due to a case sensitive variable that's not the same as it was declared.
So I'm really glad PB is case insensitive, lets me get on with coding as opposed to trying to find silly bugs.
