They're pretty similar, but TP 6 has more bugs.  The only language
changes I can remember are the addition in TP 7 of "public" and
"inherited".

Other changes -
open array & string, High & Low functions
break & continue
null-terminated strings

From (UK) PCW's Dec 1992 article, confirmed in part by memory.

Also, TP7 came with TV2.0 & TP6 with TV1.0 ; ISTR changes there.

Some things I think about  which were new in BP7/TP7

-  inherited
-  I think the heap was changed again (not sure)
 - open arrays
 - openstring parameter
 - Constant parameters
  - Public/private sections - Allows public and private
     sections of objects to be declared in any order.
  - Assigned
  - Include/Exclude
  - Break/Continue
  - Low /High
