Sorry if I have missed it somewhere here but is there a command or directive to set the default path to the folder it runs from. I am defaulting to a folder in \\\Onedrive\Documents. Thanks.

OPTION DEFAULT PATH "directory" to select the directory from where on startup you want to be able to load programs. This must be a fully specified filepath e.g. OPTION DEFAULT PATH "C:/USERS/PETER/DOCUMENTS/MMB4W". The filepath must exist.

Goksteroo said I get this....

On my Dell Inspiron laptop running W11, I get the same.

Under Device Manager, there are no COM ports listed and this is because in this laptop, there are no COM ports, only USB. If I connect up a Picomite, or in fact, any USB to serial device/adaptor, the associated COM port is correctly identified.

Quote to know how many COM-ports are aviable and num of each COM port you can use
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter

No: this shows all the comports that have ever been used not which are active. I get
&H64Fd3f200640 but only have three active ports

I said "aviable", not "active".
it means (my English is not good) that it displays all the COMports installed for the first time (used or not currently used), it was created so that the COM drivers know the first free COM number it can use.
After with key value, developer should test whether device is active or not by reading port status or sending 1 byte and wait for timeout, for error, or with your MMBasic function: "? Comports(xx)"

Also, this register key is use to cleanning all comport not active or desinstalled but always registred

Hi matherp,

Have you thought about the Pi-cromite bare metal version?
On Raspberry Pi Zero and Zero2W it would be an absolute hit.

Yes, it's been thought about. There was a Raspberry Pi version some time ago but, because of the frequent changes made to the Pi's OS, it became impractical to support it. AFAIK there are no plans to work on any versions specifically for the Raspberry Pi boards now.

I was talking about bare metal that won't change.
But the graphics version on MMBASIC on Debian for Pi Zero would be very attractive too.
Pi Zero has too little RAM for modern Linux, which can be seen at startup and when trying to open pages in the browser. He is such an ultra-cool microcontroller forced to fight Linux.

Sorry to disturb the thread.
This only occurred to me when I saw the performance of your version for Windows.

SAVE IMAGE is almost right.
Any 0A gets converted to 0D0A resulting in a corrupted image

The attached ZIP has a good and bad screen dump.
The problem starts around 1BC0

Hi,
I posted an issue on 31st Jan...just wondering if anyone else having same problem or is it just me? and ideas?

Quote only the versions up to and including the 3rd published version...(NOW with full GUI and Mouse support) work at all.
All newer versions (up-to and including pa5) open initial black window and nothing happens after that

Test code on my CMM2

'echotest
do
k$ = inkey$
if k$<>"" then print k$;
loop

test code on MMB4W

open "COM11:230400" as #2
do
k$ = inkey$
if k$ <>"" then print #2,k$;
if loc(#2) > 0 then
j$ = input$(loc(#2),#2)
print j$;
endif
loop

It doesn't work on a pico if you are using the USB.
For the pico to send data to the PC, the PC needs DTR asserted.
The pico will receive data OK, just won't respond.

SAVE IMAGE now works correctly.

But...
Changing MODE opens a new window without closing the 'old' graphics window.
I also seem to need a pause before changing modes again, probably related to the above.

I tested serial between two ports on the PC and didn't see the issue but please retest with the attached

MMBasic.zip

Also, please let me know if the mode issue has gone away (think it was related to work on sound support)

Quote el-cheapo Pendo Atom 32 bit Win10

Possibly that the graphics thread isn't fully operational before the Basic firmware starts to try to write to it. I've tried to put in an interlock but have nothing similar to test on and first time I tried something similar it didn't work.
Please report if this version now works for you.

Hi guys, newcomer here, pleased to meet you all.

Right into the problem:
FRAMEBUFFER WRITE crashes MMBasic.exe, so does PAGE WRITE FRAMEBUFFER (after having created the FRAMEBUFFER, obviously)
Others commands related to FRAMEBUFFER seem to work (WINDOW,BACKUP, etc) dispite I cannot test them, as I cannot write into the FB (at least, they do not crash). I tested the executable on two separate machines, both running Windows 8.1 (64 and 32bits). Sniffing the problem with tools from Sysinternals (ProcessMonitor) shows the video card driver is involved (NVidia for 1 of my PC) and Windows Error Reporter specifies the memory cannot be writen, but I have never had any problem with my VC driver, so I do not suspected it.
My questions then are:
-who else has this problem?
-where does the FB is created in memory? Are the PAGES created in process memory, and FB elsewhere?
Thanks for any help.
(tested on 5.07.03pa18 right now)
(sorry to mix my problem with the current COM PORTS subject, one problem at a time would be better, but hey, I'm in deep need of this wonderful FRAMEBUFFER SCROLL feature!

)

pa18. I'm in mode 9 , font 2,1 , with a US Keyboard. COLOR n,n (any n,n but lets say 15,0 for white on black) makes new typed text not visible. Old text still on screen remains visible.

MMBasic hasn't entirely locked up, as it still responds when I type EDIT, even if I can't observe myself typing. Once in the full screen editor, I can see what I'm typing again. And when I ESCape, back to invisible typing.

Restarting MMBasic clears the problem, it doesn't persist across restart.

CLS doesn't seem to know any color but black either...
