If that is sufficient, the Bronze version is very inexpensive and dead simple to use.  I also recommend this as a good multi-level teaching/learning language since you can start with middle-school level programs but using the Silver or Gold versions and the supplied libraries get reasonably sophisticated.  It is what I use for all my work.

I use TrueBasic  It’s very slo because the bottle neck is writing the output to a file on my ~ 7 year old PwrBk  (1.67 GHz clock, one CPU)  
No noticeable improvement in compiling because of the bottle neck.  Typical runs are w/ a STEP (loop) of 40k  During which I enjoy coffee.  

I’m numerically modeling a pendulum driven quasi-electromagnetically with quadratic dissipation.  I intend to describe it in an article for the Horological Science newsletter.  

It required a day of trials to apply the drive symmetrically about the equilibrium position for a short time.  (incipient Alzheimer’s)  

I keep the old (I’ve had two in-between my present one year old one) just for True Basic — Chipmunk appears too different.
