[daip] physical filename format

[Derek Moss]

Hi

I am running AIPS DEC03 on Redhat Enterprise 4, at the University of 
Southampton in the UK.

I have a load of data on disks, but can't figure out the AIPS userid of 
the owner.

The Going AIPS progammers manual says that the ZPHFIL routine creates the 
filenames by converting various numbers from inside AIPS (INVER, catalogue 
number, userid etc) into hexidecimal. This seems very sensible. But, the 
filenames that I get from in the DAxx disks are not in hex. They feature 
numeric characters from 0 to 9 and alphabetical characters from A to Z.

Is there some other level of encoding that I am missing?
Sorry if I am being dim and missing something obvious.

Thanks
Derek
