read some z80 specifications..

In general they are bits set and cleared according to the result of an
instruction
Z, the zero flag is for example set if the result of for example a sub
instruction is zero.

You use them mainly in conditional jumps

To see exactly all flags that exist, and when they are set and cleared,
check the instructions listings for the z80, for example them that is
available at ticalc.com, those are the ones I use..
