I think this is an excellent way forward on this.  I have Sybase 12.5 as 
well and could try some test cases easily (getting the house ready to 
sell, so my time is at a premium, atm). Specifically in dblib we need to 
test dbdatlen(), which i think will be obvious, and dbcollen() which is 
anybodys guess, and I think this is the important point.
