Hi, cdwrite13_vms now runs on OpenVMS Alpha V7.x, too. It seems that now the scsi timeout parameters a limited to 255. So one has to modify a few lines of the code: ************ File $41$DKA300:[ANON_FTP.CDWRITE]CDWRITE13_VMS.C;2 726 gk_desc.SCSI$L_PH_CH_TMOUT = 255; /* SCSI phase change timeout, sec */ 727 gk_desc.SCSI$L_DISCON_TMOUT = 255; /* SCSI disconnect timeout, sec */ 728 ****** File $41$DKA300:[ANON_FTP.CDWRITE]CDWRITE13_VMS_OLD.C;1 726 gk_desc.SCSI$L_PH_CH_TMOUT = 0xfffffff; /* SCSI phase change timeout, sec */ 727 gk_desc.SCSI$L_DISCON_TMOUT = 0xfffffff; /* SCSI disconnect timeout, sec */ 728 ************ ************ File $41$DKA300:[ANON_FTP.CDWRITE]CDWRITE13_VMS.C;2 809 gk_desc.SCSI$L_PH_CH_TMOUT = 255; /* SCSI phase change timeout, sec */ 810 gk_desc.SCSI$L_DISCON_TMOUT = 255; /* SCSI disconnect timeout, sec */ 811 ****** File $41$DKA300:[ANON_FTP.CDWRITE]CDWRITE13_VMS_OLD.C;1 809 gk_desc.SCSI$L_PH_CH_TMOUT = 1800; /* SCSI phase change timeout, sec */ 810 gk_desc.SCSI$L_DISCON_TMOUT = 1800; /* SCSI disconnect timeout, sec */ 811 ************ The new version is available via anon ftp from v36.chemie.uni-konstanz.de in sub-dir [.cdwrite] Good luck Eberhard
