CML tickers + preventing Option tickers from entering the data base

[rbf@xxxx]

Dear TJ and ASX Traders

Up to, and including 18 July 01, a prominent company, Coles Myer 
Limited, traded on the ASX with the ticker CML. On the 19 July 01 it 
started trading with the new ticker CMLDA and on the 20 July a second 
style of share with the ticker CMLC also began trading (with a 
considerable premium to CMLDA). I import an ascii data file using the 
ogema.format file.

The two new data files CMLDA and CMLC have been created and, as 
should be the case, no data has gone into the old CML file after 18 
July. Unfortunately, no data have gone into CMLDA and CMLC, despite 
it definitely being there in the ascii files.

Q1] can you suggest what action I should take to fix this ? (I should 
then merge the old CML with the new CMLDA ??)

Q2] My ascii files contain hundreds of six-letter tickers denoting 
stock options. How do I prevent them from entering the data base at 
all ?


For ASX traders there is a 'proper explanation' of the new Coles Myer 
Limited shares at www.egoli.com.au - it seems to go like this: CMLC 
are the 'first' 500 shares owned by shareholders. The rest of a 
shareholders holdings are CMLDA "tickered" shares ! Bloody hell!

Thanks to all
