What formula does SPSS apply to the data in an ANCOVA?

The procedure for an ANOVA is really straightforward; you compute the between group variance and the within group variance, divide your results to get an F statistic, and compare it to your critical value.

But what about ANCOVA? I can't find an exact procedure anywhere. Can someone show me a piece of code to find the F statistic in an ANCOVA? And not just using pre-built ANCOVA modules, because what I am interested in is how the resulting F statistic is obtained.

I tried researching the ANCOVA formula, but to no avail. I am expecting the formula.
