Header Record Sizes

I am generated an experiment (xlds#l) which has a load of ancillary files that go from 1850 to present (and beyond in some cases). I've just added ozone and got an error:

OPEN: File /work/n02/n02/stett2/ancil/hist/N96/O318502099RCP45.anc to be Opened on Unit 30 Exists
IO: Open: /work/n02/n02/stett2/ancil/hist/N96/O318502099RCP45.anc on unit 30
IO: from environment variable OZONE

No room in LOOKUP table for Ancillary File 1
INANCCTL: Error return from INANCILA 14
INANCILA: Insufficient space for LOOKUP headers

I think to solve this I need to increase the number of Headers — the current limit being 50,000. But when I try to increase it to 100,000 I get an error from the UMUI telling me the value should be between 1 and 50,000.

So a coupled of questions:
1) Am I correct that I need to increase the number of header records? (I could imagine I've messed up creation of the ancillary file.. Which was made using xancil)

2) If I am correct is there a hand-edit (or other way) of increasing the number of header records?

HI Simon,

The hand edit I have used in the past is

# Change maximum total number of look up headers for
# ancillary files from 4000 to 70000 (maximum in umui = 40000)

I hope that helps.
