- Use a data structure with a 30-digit packed field.
- Move your character field right-adjusted to the data structure, with
the left-most bytes of the DS set to x'00'
- Assign the packed field to a 30-digit zoned field.
- The value you want is in the zoned field.

D   packedVal                   30p 0
D zonedChar       ds
D   zonedVal                    30s 0
D len             s             10i 0
