Fanuc OMC TL Offset Param - which one?

I have a Fanuc OMC control that seems to have only 14 tool length offsets,
on a machine that has a 24 ATC...! I think someone accidentally goofed the
params and turned off some of the original TLoffsets.
I thought the minimum was 32, and max up to 200.
In any case, does anybody know which 900 param defines the number of tool
length offsets?
