Yes. First, create the export specifications that you need.
Then create your code that selects whichever spec you want.
You can set the delimiter within the Export Specification.
Example:
Function ExportTest()
On Error GoTo ExportTest_Err
DoCmd.TransferText acExportDelim, "Table1 Export Specification", "Table1", "C:\Documents and Settings\YourFolder\Desktop\Table1.txt", False, ""
ExportTest_Exit:
Exit Function
ExportTest_Err:
MsgBox Error$
Resume ExportTest_Exit
End Function
