The S370FF
w.
d format
writes numeric data in IBM mainframe format (EBCDIC). The EBCDIC numeric
values are represented with one byte per digit. If EBCDIC is the native
format, S370FF
w.
d performs no conversion.
If a value is negative,
an EBCDIC minus sign precedes the value. A missing value is represented
as a single EBCDIC period.
