HCOB 9 October 1970 What Is a Read is hereby cancelled as conflicting with existing LRH — HCOBs defining a read.
A read is a SF, F, LF or LFBD. A "Stop" is not a read.
A "Tick" is always noted and in some cases becomes a wide read.
Things that don't read won't run.
When you go around running unreading items you get low and high TA trouble.
