It may be a while before I automatically think "loop i = 1 to 10"
instead of "do i=1 to 10", but I believe it's definitely an
improvement in the language. Mike obviously tried to accomodate us
dinosaurs, but it doesn't seem to be helping (me) much. The
following erroneous code snippet produces the subsequent console log:
do i = 1 to 3
say 'i=' i
end i
[N:\nrx\jnrw\3_flowcontrol]nrc -run looptst

+++ Error: Unexpected END (no unended DO, LOOP, or SELECT)
Compilation of 'looptst.nrx' failed [2 errors, one warning]

Mike, if it's not possible for this sort of ubiquitous loop contruct
to be recognize with the 'do' keyword, perhaps it would be better to
have the warning say "Wrong syntax for DO; did you mean LOOP?" :-)
Regardless, I presume that if 'retrying as a LOOP instruction' is
successful, it would avert the other two errors, right?
