So you want to automatically create a new user profile on the AS400.
Some other system is going to sent it a USER PROFILE NAME to use for the create?
Is that it?
Is the source system an AS400?
If not, do you have standard default values for all the parms on a CRTUSRPRF command.?
It looks like the objective is to call a program on the AS400 that will do what you want.
