You are looking for a named loop - in *** you would write
it as:

main_detect:
for a in 1..pptest_w loop
   for b in 1..pptest_h loop
      pixelcheck:= getpixel(pptest_1a, a, b);
      if pixelcheck <= 0 then
      elsif pixelcheck /= 0 then
         pixelcheck:= getpixel(pptest_2a, a, b);
         if pixelcheck <= 0 then
         elsif pixelcheck /= 0 then
            collide:= 1;
            exit main_detect;
         end if;
      end if;
   end loop;
end loop main_detect;

FUNKtion;

In absence of named loops the "goto" is the most suited (not
dangerous for _exiting_ structures) IMHO...
