I'm writing code that creates quite a few thousand records and
ultimately saves them into a TXT file. In some scenarios, my record
count exceeds the Excel row limit of 65,536. In these cases, of
course, I need to dump some of the records out of Excel into the text
file so that I don't overflow.

I have no problem saving the first set of records into the text file.
What I am wondering is if anybody has any ideas as to how I can append
the second set of records onto the same text file. Let's say that my
procedure creates 70,000 records. My algorithm might look like this:

For x = 1 to 3500
'create 1st record set
Next
ActiveWorkbook.SaveAs Filename:=OutputFile, FileFormat:=xlText
For x = 35001 to 70000
'create 2nd record set
Next
'Append data to first .txt file - This is where I am stuck

Is there a way to write these records into the text file without
bringing it back into Excel? I tried using Word, but it was
prohibitively slow and I don't know much about VBA in Word. I could
use Access, but nobody in our office besides me has any experience in
Access and this will be a shared app, so I'm trying to keep it as
simple as I can.

Thanks,
Randy Eastland
