Binary data

For binary data you can specify, on the DFHCNV TYPE=FIELD macro, either:

DATATYP=BINARY
Start of changeThe default format for binary data received by CICS® on System/390® is big-endian; that is, multibyte numerical values have the most significant byte values first (in the lower machine address).End of change
DATATYP=NUMERIC
Start of changeThe default format for binary data received by CICS on System/390 is little-endian; that is, multibyte numerical values have the least significant byte values first.End of change

The default binary format can be overridden. It is therefore important that you code a DFHCNV TYPE=FIELD macro for every binary field. If the resource can be accessed from CICS Transaction Server for Windows, you must set the default binary format to that used by CICS Transaction Server for Windows.

You should ensure that the format of each individual binary data field--BINARY or NUMERIC--is consistent across all INTEL platforms.
