Hi johnno56.
You're trigger finger might have something to shoot at if the critters were larger. As it is now, it's like shooting a 155mm Howitzer at a mosquito. Yes it will get the job done, it you can find/see the beastie.
As to the other software, it's good old (no longer developed) BlitzPlus basic. The only advantage that BlitzPlus still has over many other languages, are the built in GUI gadgets (buttons, list boxes, radio buttons, text boxes, etc) just like those seen in Windows apps. As noted, BlitzPlus basic is also very fast.
There's always JustBasic that has many GUI features, but is sooooo muuuuch slower. In the end it's more like an interpreter speed wise, vs a truly compiled language.
