It is NOT official.  See my earlier repsonse concerning HP's policy on
unsecuring code.

Unless the line is labelled; in that case a fourth word exists as an index
into the symbol table (for the label).

Yes, conceptually simple, but VERY time consuming.  A lot of work went into
BASIC to make it fully relocatable, reentrant, traceable, fast, etc. etc.
Therefore the internal representation of a program is very complex.
The information presented here is mostly correct, but the proper solution
to the problem is to have HP unsecure your program.

At this point in time it is not possible to distribute the unsecure program.
