Now onto the next OSWORD call, &63, which the VFS equivalent of ADFS &73, which has the effect of reading the last error number and disc address where the error occurred. In terms of ADFS, this OSWORD call is most useful when verifying a block of sectors. It will give the exact sector number where a verify error occurred. This information isn't reported by OSWORD &72 when using the verify SCSI command code, but since the LV-ROM player doesn't support the SCSI verify command, it doesn't really matter.
