This is simply not true. IM states very clearly that one may modify
the teLength and hText fields. The catch is that you *must* call
TECalText() before performing any further operations with the TEHandle.

There is a one sentence indication on IM Vol I page 378.
There is the reference to TECalText() on page 382.

Set the two fields in question, then call TECalText(), then InvalRect(),
then TEUpdate() and things should work.
