please tell me a program to convert sas7bdat file to xpt file.
Please look in the documentation for XPORT or Proc CPORT. The filename extensions are not that critical. Both approaches create transport files to interchange between versions of SAS.
Where can i find the document? You got some link??
Why don't you give the search facility on support.sas.com a try?
You'll find this information in the Base SAS documentation.
Have you tried pressing F1 on your keyboard?
