The edit that Mike Schwartz mentions called rj0 has been around
since 4.1 (second set of gray pages 12-18), along with "rj," "rjnum,"
and "rjminus."  If there was a different one called 0rj, I missed
that one - maybe that came out in 4.8?

I tried Ken's much simpler "0rj" above and the one that we have for
"rj0," which is:  [{ <0>!" "! }]  [{ # }]

and they behaved exactly the same for both direct data entry and for
the following processing posting tests on a field 1 with length
10 (with fp5.014):

1.
Then: ab(10,.0)="4"; 1=ab; end
Running rreport using this sets field 1 to "0000000004"

BUT

2.
Then: 1="4"; end
Running rreport using this sets field 1 to "         4"

So if you, for some reason need to assign literals to an rj0
field in processing and want zero padded results, remember to
use another intermediate field, as in #1 above, or do some
math as you as assigning as in:  1="0" + "4".  I don't think
I've had a need to do that so much as assignment to a dummy
field that needs the edit as in:  ab(10,rj0)="0" + "14".
