this short program crashes my PRIME

Hello,

Not your fault... There is a bug in the return call in the for loop which is causing the issue...
a workaround while waiting for the fix is to copy your 'output' in a variable (C will work) and then to do a break; to exit from the for loop...
then return your C....

note, you can do:
if A<=R<=B then break; end;
this should work
