| Feature Request - SOUND breaks on/off |
|

Could you add a function or statement that would turn on/off the brief break (silence) after a SOUND command? You could have this ON by default, so things wouldn't be any different than they are now. But, if the programmer wanted to, they could turn this OFF, to make old style SOUNDs not be so "buzzy". Maybe something like _SoundBreakOn and _SoundBreakOff or perhaps _SoundBreak(x) where x could be 1 or 0.
As an example, try running this code in QBasic (DosBox), in QB64PE 3.6, and the current (at the time of this writing) QB64PE 3.11.
Notice the difference in sound quality for each. In QBasic it is loud and clear. In 3.6 it is slightly buzzy/clicky. In 3.11 it is VERY buzzy.
Code: (Select All)
For w = 1 To 3
For q = 100 To 2000 Step 10
Sound q, .2
Next q
For q = 2010 To 110 Step -10
Sound q, .2
Next q
Next w
End
There is an old game I started but never finished back in the 1990's (in QBasic), that I have started to work on again in QB64PE. It has a lot of "retro video game" style sounds that do things similar to the code above. I've been compiling it with QB64PE 3.6 because in newer versions the sound quality is TERRIBLE, but in 3.6 it is decent. I would much rather use the current version (QB64PE 3.11), the only thing stopping me from doing that is the poor/buzzy sound quality.
If there was a command like _SoundBreakOff that I could add to the start of my program, which would make the sound work as it does in 3.6 (or better yet, if it is at all possible, as it does in QBasic), I would be able to use the current version, which would be fantastic!!
Thanks so much for QB64PE - you all are doing some amazing work!!

| ARRAY declaration in GOSUB routines. |

I have noticed the following.
OPTION _EXPLICIT
[main code]
CALL test
END
SUBROUTINE test
[variable declaration]
[arrays declaration]
[CODE in which arrays are not used]
GOSUB section 1
[CODE]
section 1:
'[variable declaration]
'[arrays declaration]
[CODE in which arrays are used]
RETURN
END SUB
So, OPTION _EXPLICIT requires the declaration. If not, it get error. However, for it, it's the same that:
[variable declaration]
[arrays declaration]
is put at the beginning of the main code of the subroutine, or at the beginning of the GOSUB routine. The important, for it, is that the declaration takes place before the use of varriable and arrays to be declared.
But I noticed that if I put [arrays declaration] in the main code of the subroutine and not at the beginning of the GOSUB routine, then I have an OUT OF RANGE error executing the program with the reference to the lines in which the arrays are used.
Why?
The GOSUB routines, regardless if they are used in the main code or in a suroutine, are not considered as a part, respectively, of the main code/subroutine?

As you can see, I'm in the mood for questions.
Look at this:
Code: (Select All)
OPTION _EXPLICIT
DIM myArray%(5)
PRINT UBOUND(myArray%)
the result is "5".
Fine.
Look at this:
Code: (Select All)
OPTION _EXPLICIT
DIM myArray%
PRINT UBOUND(myArray%)
This is less "fine".
1. If OPTION_EXPLICIT is activeted, it says "myArray" is not defined.... why?
2. If OPTION_EXPLICIT is deactiveted, the result is "10"... why?

| QBJS v0.8.2 - Release |

Hi all,
I've just published a patch update to the last QBJS release. This fixes a couple of issues related to exported programs. A dependency js file was not being included in the export and was preventing _Inflate$ and _Deflate$ from working correctly in the exported program. Also, an update was made to the OPEN keyword so that it could open resources directly from the server for an exported program.
This had the interesting side-effect / new feature of being able to use OPEN to read directly from external URLs. Here's an example with more details:

Hi, I need an explanation about the command "CLEAR".
DIM a% locates a part of memory for the variable a%, that is empty.
a%=1 give to the variable a% the value 1.
What does CLEAR? Does it makes a% empty again, or does it deletes the memory located for a%, virtually "deleting" the command DIM a%?

| suggestion: create a custom puppy linux distro that includes QB64PE out of the box |

I am NOT a Linux or a Puppy Linux guru, but I am drawn to the idea of an self-contained OS that runs on a thumb drive, and comes prepackaged and preconfigured with a set of software to do a certain job (e.g., play emulated games, for artists, video production, robotics, etc.)
A Puppy Linux "QB64PE" distro would be pretty cool, especially for people who might be interested in testing their QB64PE programs in Linux but don't have the knowhow / time / patience to dive into Linux proper.
Anyway, I thought I'd share this link with anyone inclined to explore spinning off their own Linux distro...
PS Along those lines, there is at least one Puppy Linux distro - RasPup - made to run on Raspberry Pi.
A Raspberry Pi QB64PE distro would be pretty neat & useful!
Some reading:
If this gives someone a cool project to jump into, great.
If not, I won't lose any sleep, just thought I'd share that idea...

| accessing the CLI in a prog |

How does one access the C Prompt (CLI) from within a QBPE programme? I don't see any functions like CMD or COMMAND, but I know it can be (and is) done frequently by members. I've tried to interpret what they did, with no success. How do I get to put Shell "c: dir" (and others) into my programme? (maybe another lesson about CLI access etc ?)

| Item$ Tools for Getting Strings to Behave Like Arrays |

Allot of people complain you can't use arrays in UDT's but you can use strings and a string can function like an array, in fact they can be more dynamic than arrays! see InsertItem$
Luke gave us some nice routines for strings behaving as numeric arrays, here I will deal with variable length strings in a bigger variable length string.
These Item$ tools are for a string of variable length strings separated by Delimiter$
Code: (Select All) _Title "Item$() and SetItem$ test demo" ' b+ 2024-01-28
' another test demo of array like strings
months$ = "February, March, April, May, June, July, August, September, October"
Print Item$(months$, ", ", 1)
months$ = InsertItem$(months$, ", ", "January", 1)
Print months$
months$ = InsertItem$(months$, ", ", "December", 12)
Print months$
months$ = SetItem$(months$, ", ", "November", 11)
Print months$
Print "9th Month = "; GetItem$(months$, ", ", 9)

lastd = d + 1: d = InStr(lastd, Source$, Delimiter$)
