Sequential File creation.

Creating a sequential file for 1099's to send to the IRS.

I am getting 2 mystery chars @ the front of the record.

When I open the file via notepad the first is displayed as STX and the second looks like an l with the caret on top. 

I move spaces to the 01 Level and write each different 01 level record.

I am doing this for W2's with no problem.

Is there some kind of record size limit or ???
