Question : RPG III program will not execute inside a RPG IV program (error message: MCH3401)....

I am trying to call a rpg III program and it is failing. The parent program is RPG IV and I am running "Turnover" on the iSeries v5r4. "dsr596dbe" is the name of the RPG III program.

The things I have tried: 1. Made sure that my library is in the library list. 2. Switched from lower to upper case with the rpg call.

    For a system pointer, it can not be resolved to object dsr596dbe, type and
  subtype X'0201', authorization X'0000', because either the named object was 
  not in any context referred to or the correct object was located but the    
  user profile did not have the required authority.

Answer : RPG III program will not execute inside a RPG IV program (error message: MCH3401)....

Does the user profile that you are running under (at runtime) have rights to execute program DSR596DE?

Silly things to check:

Is the program name spelled right? 596/569 is an easy transposition, for example.
Does something in the runtime job change the library list in a way that removes your lib? When you get the error, look at the job's libl right then.
