Re: [Quickfix-developers] weird code

[Hozaifa A. A. <hoz...@ve...>]

Azmat,

The line ur asking is getting the group of data number of times coming in a
response. this group contains tag 269, 270 and some more. tag 268
(NoMDEntries) is the number of times. Code is correct just start the loop
from 1 not zero.

Regards
Hozaifa Akber Ali
