Not true.  BASIC-PLUS, at least starting with RSTS V5 or thereabouts, *supports* BP2 syntax as an alternate option.  But it does not insist on it and it still supports the old syntax as well.  Here is RSTS V10.1:

list
BPTEST  11:30 AM        26-Jan-18
10 & "hi there" :
   & "line 2, with <LF> continuation"
20 end

Ready

run
BPTEST  11:30 AM        26-Jan-18
hi there
line 2, with <LF> continuation

Ready

For BP2, & as shorthand for PRINT is not allowed, : must be replaced by \, and continuation lines must be &<crlf> rather than <lf>.  If you do that, the file will still work with BASIC-PLUS in RSTS/E (but not on V4A).
