RE: Limitation of passing parameters into service program class.

Yes, I was thinking you would write the intermediate program in an AS/400
ILE language, then use Toolbox ProgramCall to call that intermediate
program.  Program call doesn't know or care that the middle program will in
turn call the actual service program.  There is no way to manipulate
ServiceProgramCall to directly call a service program with more than 7
parms.

Dave,

      I am still confused. Should I write the intermediate program in a
ILE language and then use the program call?. I am trying to use a system
service program as shown below. I think you will have to throw some more
cents worth of your knowledge to make me understand :-)

****************************************************************************

******************
ServiceProgramCall sPGMCall = new ServiceProgramCall(myAs400);
      sPGMCall.setProgram("/QSYS.LIB/QRDARS.LIB/QRLRRAPI.SRVPGM",
parmlist);
        // Set the procedure to call in the service program.
          sPGMCall.setProcedureName("QrlrRetrieveReportKeyList");
                 // Set the format of returned value.  The program we
call returns
                  // an integer.

sPGMCall.setReturnValueFormat(ServiceProgramCall.RETURN_INTEGER);

          if (sPGMCall.run() != true)
          ...

I am not a guru but I will throw in my two cents worth.  To solve this
problem via Toolbox ProgramCall or ServiceProgramCall you will have to
write an intermediate program.  The client would stuff all parameter data
into a single parameter and call the intermediate program.  That program
would parse the data into multiple parameters and call the real program /
service program.  On the way back the reverse is done.  The intermediate
program gets return data from the real program / service program and stuff
data into a single parm that is returned to the client.  If I wanted to
make the intermediate program generic, the single input parm would ben
something like:
     int numberOfItems
     int[] itemSize
     char[] items
I would also enforce format to be something like the first item is the
library name, the second item is the program name, the third item is the
entry point (size = 0 if calling program versus a service program), etc.

Gurus,

     Please respond? I tried passing multiple parameters in the same
buffer, But still it errors out. All Ideas welcome.

Hello,

      Please oblige if this question had been raised before in the group.
I am trying to use a
Service program which needs 12 parameters. But the manual says that I can
pass only 7 parameters into the SERVICE PROGRAM CLASS. How can I tackle
this
situation?

Thank you.

Naveen
