Binary data
The DATATYP keyword on the DFHCNV TYPE=ENTRY macro specifies the default format for binary data received by CICS® Transaction Server for z/OS®.
- DATATYP=BINARY
- Specifies that the default format for binary data is big-endian; that is, multibyte numerical values have the most significant byte values first (in the lower machine address).
- DATATYP=NUMERIC
- Specifies that the default format for binary data is little-endian; that is, multibyte numerical values have the least significant byte values first.
The default binary format can be overridden. It is therefore important that you code a DFHCNV TYPE=FIELD macro for every binary field.
