JAH 2.1 has been posted on my web site, for those interested.
The URL to download is http://bgilon.free.fr/apple2/JAH2.1.zip
Briefly stated it provides the features below in addition to those offered
by v2.0.2.
The included JAHELLO Applesoft program is a sample progarm for you to get
the idea.
The source file on teh disk image is JAH2.1.s (Merlin format). 
New bits meaninful for specifying operation mode:
. b1 for specifying an Applesoft subroutine (by its begin line #) to
initialize variables objects required by the computation itself. Helpful
when a DEF FN function is required or to initialize constants variables or
arrays, particularly when b7 is itself set (meaning  that the computation
should be handled with a completely separate data segment).
. b0 for specifying a list of variables that should reside on top of SVM
(simple variables memory segment, thus speeding references to those
variables from the program flow). This is an imported mechanism from
Peersoft.
. b7 (introduced in JAH2.0.2) for dealing with a private data segment
enforced for every USR subsequent call handling (size is preset to 512 bytes
but can be tailored to one's own requiredment by just reassmbling the source
file). 

This is the JAH final release as a standalone UPO (unidentified programmmed
object ;-).

Peeersoft next update (due to be released before August this year) will
include the PF (Procedural functions) feature.
