You - what Dave says.

You could make the routine more generic if you needed it but this is
the simple way to map a single field.

Yes, for example (to make it more generic), you could create a
15-character field and overlay it with a 15-digit (zero decimal) zoned
field. Then, move zeroes to the zoned field before right justifying the
character data into the character field. Then, you just have to divide
the resulting zoned decimal number (into another field) by the number of
desired decimal places that you got from SYSCOLUMNS.

To get the leading zeros and right-justify the character value in one go, use EVALR with a character variable initialized to zeros.

dcl-ds cvtzoned qualified;
c char(15);
n zoned(15) overlay(c);
end-ds;
dcl-s zeros like(cvtzoned.c) inz(*all'0');

evalr cvtzoned.c = zeros + '1234N';
dsply (%char(cvtzoned.n));
