I found a program to run Qbasic code on an Android device. I will describe the effort in the coming days with pictures:

Android Basic costs $3.20 at this link to use on Android devices: https://play.google.com/store/apps/details?id=and.bas" target="_blank

Here's the command structure which is close to QBasic: http://androidbasic.ninja-web.net/man/indexe.html" target="_blank

LOCATE can use x,y 0,0 or y,x 1,1 in the Menu Settings. Font size should be 24 on 7" tablets and 16 on phones.

### Re: Running Basic on Android

The Android-Basic menu includes Run.c to compile and run faster, Load a BAS file, Run, i which is slower and Settings:

Settings allows you to choose which font and LOCATE syntax you wish to use:

Font 16 works for phones, but 24 looks better on my tablet. Larger makes the screen scroll with text all over the place.

The default LOCATE syntax can be changed from x, y 0,0 to y, x 1,1 which Qbasic uses.

Font 16 is pretty small. The box around the calendar month uses LINE a bit differently: LINE (80, 40)-(460, 264), hsv(160, 25, 80), b

Font 24 is larger for tablets, but I need to redo the LINE coordinates for the box:

Most of the code is pure Qbasic, but the SUB programs were converted to GOSUB calls:
Thanks to Pete from the N54 Qbasic Site for help converting the code! http://www.network54.com/Index/10167
