\fIK\fP, \fIM\fP, \fIT\fP or \fIS\fP may be appended to denote
kilobytes, megabytes, tracks or sectors. If provided, a specifier
must immediately follow the numeric value with no whitespace. For
convenience upper and lower case are both accepted and only the first
letter is significant, thus 2KB, 8MB, 1000trk and 16sec are valid
