I have some FORTRAN subroutines for importing records from
CFS which form part of the Strathclyde Electrophysiology Software
package. You can download the source code from my Web page

Alternatively, CED might be willing to help. They have a CFS support
library. Their Web page is: http://www.ced.co.uk
