[Implemented] Commas in 'select' statement?

I had a quick search for something similar to this and found nothing, which was really suprising.
Code: Select all
Select Somevar
case 1,2,3,4
; Do something
case 5,6,7,8
; Do something else
endselect
This would be incredibly handy, at the moment I'm forced to use functions to execute the same code in two different 'select' situations.
Thanks

you're not the first one who wishes this...
Alternative syntax

I've seen some languages implement it this way:
Code: Select all
Select Somevar
case 1
case 2
case 3
case 4
; Do something
case 5
case 6
case 7
case 8
; Do something else
endselect
Unfortunately, that doesn't work as desired in PB. BUT that kind of syntax might be easier for Fred to implement.

Of all possibiltys the worst methode (and take much more writing-time).
When i remember right, C use something like this, but there you must exit a case with a "break" or it will run in the other case-statement...

i'd settle for the more or less common basic syntax:
case 1,2,3
case 3
default
etc.

You could also just use
If...ElseIf...EndIf like so:
Code: Select all
If Somevar>0 and Somevar<5 ; case 1,2,3,4
; Do something
ElseIf Somevar>4 and Somevar<9 ; case 5,6,7,8
; Do something else
EndIf

I need lthis feature.
It's not indispensable but it's frustrating to fill the code with
if...
if...
if...
if...
A solution maybe the use of commas (is the best solution) or the use of a 'break' instruction like in the C language.

It's no more frustrating than using multiple Case statements.

PureBasic does have a Break command (see the docs).

But does not need breaks in Select/Case, and hopefully it stays like that.
However,
case 1,2,5,9 TO 15,etc would be nice.
But first: Floats, fixed strings, thread safety, etc!
