(continued)
Returns TRUE if edit buffer could be allocated, or FALSE if insufficient
Outputs:
memory to allocate edit buffer. This routine always returns TRUE if hText
is passed in with the handle to a text buffer.
teRec is initialized with text edit state. teRec must be allocated statically to
maintain state between calls to the text edit routines.
Window w must already be open. Handle hText must not be locked.
Assumptions:
May cause heap compression.
Side Effects:
All versions of the TI-89 / TI-92 Plus.
