I have DATA statements working on ARM processors, including the Raspberry PI.
I am testing changes to the QB64 install script that will detect whether or not it is being installed on a ARM or RPI, change the required files and download the prerequisite libraries, which does not occur now.
If you want to test this script on your RPI, let me know and I will post a copy of it here.
The only issue I am running into is getting InForm to run on an ARM processor. QB64 so far is fine.
No bug really, Data statements work everywhere except where you tried it in a Pi apparently.
