-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, April 22, 2004 5:05 AM To: [EMAIL PROTECTED] Dear all Rietvalders, Can anyone know how to delete the holding parameter (F option under the atomic parameter menu in GSAS)? since the program does not allow me to remove them even after pressing "D" for those variables? They are still there anyway. many thanks stephen
