</cite>The long string you gave for ClOrdID translates to 04C6A29EBAD1E5BB(base16). You're expecting 4295075805(10) = 000000010001A7DD(16) No matter how you rearrange the hex digit pairs, those will never match. It's clearly not a byte ordering problem. </cite> Then that means that the other program is "lying" to me, which _is_ possible I guess since it appears to have other problems. I tried the unpack string you mentioned : 
>> unpack 'a a n N Q> a*'

[download]
but I get : Invalid type 'Q' in unpack at /opt/devel/mdscripts/PerfAgent/lib/enxtUtpDirect.pm This is (I believe)because I'm not using a 64bit perl and I can't because of some PERL packages I am using. Given this, can I use something other than 'Q' ?? Thanks very much for the assistance, it is much appreciated
