or are you learning about something more modern and in current use and just referring to a programmable device as a "PLD".
PLDs still exist but aren't used that much anymore. AFAIK there aren't any books on simple PLDs like 22V10s. The datasheet will tell you everything you need to know.
So a CPLD, which is much larger than a PLD. You'll probably want to do as wwfeldman posted and read the data sheet, but you'll probably also want to get a book or read an online tutorial on VHDL or Verilog/Systemverilog as a way to write the hardware description of your design. I doubt you want to use some ABEL variant as that is basically a dead end in usefulness.
