Flying a Holding Pattern

How do you fly a Holding Pattern when requested by ATC? On my PSS A321 a holding Pattern is built into the FMC; however my Fokker 70 does not have that feature. If I start 'wandering' about the sky at the Mayfield VOR someone is going to get very upset :). I just wondered if the Holding Pattern has a set routine written down somewhere, or if you are meant to go to a quiet place and practice for a month or two?Now that SB3 is out I'm thinking about going Online again; I remember back along ATC requested my to fly a HP, as I had no idea how to do it - I just hit the 'P' key and waited!!! - my Controller was quite upset (rightly so) and I haven't flown Online since. Thought I'd better do some 'homework' first this time.KenSomerset, England
