In the schedule I linked to, no pair of players meets more than once in a foursome. So just convert the foursomes to doubles games:
ABCD to AB vs CD, EFGH to EF vs GH, etc.. Doesn't matter how you do this, it will always have the property that no pair of players meets twice in a game.
Note that uppercase and lowercase players are distinct, so 'A' is not the same player as 'a'.
