Re: [C400-L] intercept parameters to service program procedure

[Dave McKenzie <davemck@xxxxxxxxxxxxx>]

I wonder if you could get around the binder's problem with a 2-stage method:  
have your service pgm do an external call to another pgm, passing the same 
parms, which in turn calls the procedure in the OS/400 service pgm.
