If EBCDIC is the native
format, no conversion occurs.
Note: Any time a text file originates
from anywhere other than the local encoding environment, it might
be necessary to specify the ENCODING= option on either ASCII or EBCDIC
environments. When that you read an EBCDIC text file on an ASCII platform,
it is recommended that you specify the ENCODING= option in the FILENAME
or INFILE statement. However, if you use the DSD and the DLM= or DLMSTR=
options in the FILENAME or INFILE statement, the ENCODING= option
is a requirement because these options require certain characters
in the session encoding (for example, quotation marks, commas, and
blanks). The use of encoding-specific informats should be reserved
for use with true binary files. That is, they contain both character
and non-character fields.
