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.
 |
Warnung: 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.
