You can generate single or multiple interface objects in either online or batch mode by
using the function the direct command SYSRPC
SGMASS.
You generate interface object from subprograms or parameter data areas (PDAs).
This section contains information on:
You can enter the SYSRPC SGMASS direct command
at any Natural command prompt for generating interface objects online.
The section below contains information on:
The syntax that applies to the SYSRPC SGMASS direct command
is illustrated in the diagram below:
SYSRPC SGMASS [name] [compression]
|
The syntactical items name and compression are explained in the section Name Specification and Compression.
The SYSRPC SGMASS direct command produces a report that
lists the interface objects generated with the command as shown in the following
example:

SYSRPC - Interface Object Generation in Library SAGTEST
Generation Criteria:
Object name or range: RPC*
Compression: 1
Generation Results (sizes in bytes):
Number of objects found: 8
Maximum send length: 200228
Maximum receive length: 1024192
Object Type Send Length Receive Length Message
-------- ---- -------------- -------------- --------------
RPCCALL1 N 209 202
RPCCALL2 N 219 240 Compression=2
RPCCALL3 N 204 193
MORE |
The report is organized in three sections, which contain the following information:
Generation Criteria:
The criteria based on which the interface object(s) were generated: a single object
name or a range of names (here: RPC*) and the compression (here:
1).
Generation Results (sizes in bytes):
The number of objects selected for the interface object generation.
The maximum buffer sizes all generated interface objects require for sending and receiving data from the client.
Object List:
The name and type (here: N for type subprogram) of each generated
interface object. The buffer sizes each object requires for sending (Send
Length) and receiving (Receive Length) data from
the client. A possible comment on each generation of an interface object in the
Message column. In the example above,
Compression=2 indicates that object RPCCALL2 was not
generated with Compression 1 as requested in the command. The object list is sorted
in alphabetical order of object names.
If the MORE prompt appears, choose ENTER to scroll to the end of the report.
If the interface object generation fails for single or multiple objects, the report shows the number of objects affected and appropriate error messages.
You can specify the objects (subprograms or PDAs) to be selected for interface object generation and the type of compression to be used:
You can specify an object name or a range of names. The specification of an object name or a range of names is optional.
 |
Warning: If you do not specify an object name or a range of names, with few exceptions (see below), all subprograms or PDAs in the current library will be converted to interface objects. |
Valid name specifications are described below where value is any combination of one or more alphanumeric characters:
| Input | Objects Selected |
|---|---|
| * |
All subprograms or PDAs. This is the default setting. |
| value | A subprogram or a PDA with a name equal to value. |
| value* |
All subprograms or PDAs with names that start with value. |
| value< | All subprograms or PDAs with names less than or equal to value. |
| value> | All subprograms or PDAs with names greater than or equal to value. |
In the Natural system library SYSRPC, SYSRPC SGMASS exempts
from interface object generation all subprograms with names that start with any of the
following prefixes: RDS, RPC, NAT, NAD or NSC.
In user libraries, SYSRPC SGMASS exempts from interface
object generation the subprogram NATCLTGS.
You can specify any of the following compression types: 0, 1,
2. The specification of compression is optional. The default type used
for interface object generation is 1.
