Subject: c/EVAL for loop counting

The Enhancer 1.3 manual p 2-12 gives the following example
for use of "c/EVAL" to count loops in a script:

    .key loop/a
    .bra {
    .ket }
    echo >env:loop {loop}
    lab start
    echo "Loop #" noline
    type env:loop
    eval <env:loop >NIL: to=t:qwe{$$} value2=1 op=-?
    type >env:loop t:qwe{$$}
    IF val $loop GT 0
    skip start back
    endif
    echo "done"

In practice, the example fails when eval is called.  ram:env/loop was
correctly set up beforehand, and ENV: assigned as RAM:ENV.
eval <env:loop - 1 to t:qwe{$$}   also fails.  The following also fails from
the Shell along with numerous permutations:

> setenv loop 5
> type env:loop       ; correctly returns 5
> eval <env:loop + 2  ; returns 0 instead of 7

Can anyone help with the proper syntax here?
Commodore?
