How to change the amount of rows in a listing

[eluser]ozstar[/eluser]
Hi,

I want to change a listing of categories which at the moment go to 10 rows, then one has to go to the next page etc for another 10 and so on for several pages.

I wish this list to be 50.

I have looked in Pagination but there does not seem to be any number which suggests 10 anything.

Any ideas where I should look please?

Thanks

John
