AS400FILE.setRecordFormat() does not handle some types

[jeber-ibm]

#256 and #257 fixed a problem where AS400File.setRecordFormat did not handle the boolean type.

Looking at the possible types, the following DDS field IDs may also need to be supported.

D Digits only
I Inhibit entry
M Numeric only
N Numeric shift
W Katakana
X Alphabetic only (character)
Y Numeric only

1 Binary large object (BLOB)
2 Character large object (CLOB)
3 Graphic data large object (DBCLOB)
4 Datalink
6 Decimal floating point
7 XML
