At IPL, during RACROUTE REQUEST=LIST processing, the REQUEST=LIST and REQUEST=VERIFY macros are invoked by RACROUTE. If one fails, RACROUTE returns its own return code and the return and reason codes of the called macros. For example, if the RACROUTE return code is 4, and a called REQUEST=LIST return and reason codes are 0, this means that the class is not in the router table and the REQUEST=LIST processing was not done. The message is issued to both the operator and the security console when, for example, there is an error creating an ACEE during REQUEST=LIST processing.
