Appending to a file with run-time error '54' Bad file mode

[blisspikle]

Hello,

I am getting a run-time error '54' Bad file mode when I run the
following code, I will comment where it happens. What I do is save two
rows of data out to a .csv file with the file in the format of...
FILE_2006_11_03.CSV . This code works just fine on a Windows 2000
running Excel 2000. I am using a Windows XP with Excel 2003 now.

It happens on a line that says "Write #L_column, V_data;". The
L_Column would be "2" in this particular case, and V_data would be data
like "1" or "0". If I debug I can pull the cursor up a couple lines
onto the line "Open V_Param(1) & L_filename For Append Access Read
Write Lock Write As #L_column" and it gives me an error saying the file
is already open. If I put in a line to "Close #L_Column" in before the
line where I open the file, then everything works okay again.

Why do I have to close the file and reopen it? It worked just fine
before?

Thank you,
