i only have Ashes 06, so i can't tell how to edit bowling on ICC 3 or 2008.
since bowling comes right at the bottom of a player's data, and since ICC 3 was a significant upgrade over Ashes 06, then i suspect the codes for bowling are not located in 'row 80' but a few rows down, as there could well be new additions as far as codes are concerned, thereby pushing most things down. i think allrounder18 suggested for ICC 2008 the bowling was to be found in row 84.
the row below bowling you should find the numbers 36,5 in succession. i think thats either the last two values of a player or the first two values.
cottager is supposed to be getting ICC 2008 in early September so if everyone else finds locating the bowling too difficult i'm sure he'll provide the insight.
