New message definition file wizard, COBOL file option, select the physical properties reference material.
When you are using the option COBOL file in the New message definition file wizard to create a message definition, the following are the list of panels you will be presented with:
You require "EBCDIC Custom" if instance messages in an ASCII code page use EBCDIC-style embedded signs. Otherwise, ASCII or EBCDIC does not select the "Sign EBCDIC Custom" check box for elements and, at runtime, the type of embedded sign is determined from the code page of the instance message.
For STD or OPT, COBOL BINARY data-items (including USAGE COMP, COMP-4, or BINARY) have maxInclusive and minInclusive facets created conforming to their PICTURE clause (for example, PIC S999 = min -999, max 999).
For BIN, BINARY data-items behave as if created with USAGE COMP-5. No facets are created, the logical type of each element created (for example, xsd:short) gives the implicit maximum and minimum values that may be handled.
When the data structure is initialized in this way, the resultant message can give rise to parsing errors because some fields contain a value that is not valid for the data type of the field. Selecting the box enables you to treat any fields that have been initialized in this manner as NULL values and will enable the parsing to succeed.
You specify the initialization character using the Null character control, the default value for which is the SPACE character. Setting these controls will result in all global elements having their Nillable property set, their Custom Wire Format Encoding Null property set to NullLiteralFill, and their Custom Wire Format Encoding Null Value property set to the specified character.
Under normal collation sequence rules, use 0x00 for low-values and 0xFF for high-values.
