EDI-C-EDI-EXTENSION
For outbound messages, the client program should specify OM-S-ONFILE-STRING
as the syntax of an attribute when the memory storage space might be insufficient to
accommodate the value of the attribute. The client can specify this syntax for
specific strings when the accumulated length of the strings might overflow the total
string area specified in the max-table-data parameter of the GPI_INITIALIZE_
procedure call.
For inbound messages, the Gateway Interface Process automatically specifies OM-
S-ONFILE-STRING for those strings that exceed the value in the max-table-data
parameter of the GPI_INITIALIZE_ call or that exceed the maximum length
specified in the max-in-memory-string-len parameter of the
GPI_MT_START_TRANSFER_IN_ call.
Attributes that have the syntax OM-S-ONFILE-STRING are treated as long strings.
regardless of their actual length: that is, they are treated as if they were longer than
the specification of the max-string-len parameter of GPI_INITIALIZE_. Thus, you
can use only the procedure calls GPI_OM_READ_ and GPI_OM-WRITE_ to read
and write the values of strings that have the syntax OM-S-ONFILE-STRING.
EDI-C-EDI-EXTENSION
This class of object is provided for future extensions to the EDI messaging defined in
this document.
Table 3-103
describes the attribute types for this class and the syntax, length, and
number of values for each type.
Some attribute types have additional value characteristics, as shown in Table 3-104
.
