Hi!
I would like to know how a cancel-replace message format would be?

Would it be like a CMS format ?
viz.

Event OrderQty CumQty LeavesQty

NEW 1000 0 1000
Execn 1000 100 900

[Repl… 1000 100 900]
[ 500 0 400]

here the fields will be repeating (ie. 38=1000,38=500…)

OR

Event OrderQty CumQty LeavesQty

NEW 1000 0 1000
Execn 1000 100 900

[Repl… 1500 100 1400]
this is what the specification says, unless i am making a mistake)

problem is I have seen messages given in the 1st style.

I would greatly appreciate any info on this asap .
Thanx,
Saraswati
