I am new to GALS (and PALS) and just recently successfully flashed my first
GAL16V8A using PALASM to compile and an old EEPROM burner.

I am using it to trigger a data bus read for a given set of addresses.  I
hacked the equations by looking at examples which seems to work well.

Now I am struggling to implement a flip flop which I think should be a
trivial task.

The output (Z) is required to toggle every time there is an address match.
i.e. every time X has a positive going edge.

So far I have this

/X =3D /WE * /CS * J*/I*/H*/G*F*/E*/D*C*/B*A + ;Addr 225 [8A25]
/WE * /CS * J*/I*/H*/G*F*/E*/D*C*/B*/A +;Addr 224 [8A24]
/WE * /CS * J*/I*/H*/G*F*/E*/D*/C*B*A  +;Addr 223 [8A23]
/WE * /CS * J*/I*/H*/G*F*/E*/D*/C*B*/A  +;Addr 222 [8A22]
/WE * /CS * J*/I*/H*/G*F*/E*/D*/C*/B*A +;Addr 221 [8A21]
/WE * /CS * J*/I*/H*/G*F*/E*/D*/C*/B*/A ;Addr 220 [8A20]

y =3D /X;

which works well but the following fails to compile.

Z =3D /Z;
Z.clkf =3D X;

Hoping someone may be familiar and set me straight.
