<<We get reason error -712 subsystem 104 on a call to HPGETPROCPLABEL to load MODULE B only if MODULE A was previously loaded. Can anyone point us to or actually provide the meaning of these returned values.>> Subsystem 104 is "Native Mode Loader". Error 712 is "Duplicate data symbols cannot be replaced across different load points (LDRERR 712)." Cause: "A data symbol was found while dynamically loading a library which requires a replacement of a previously bound duplicate." Action: "The message gives the file and the SOM in which the current data symbol exists. Compare the data symbol declarations in both SOMs. The data symbol from the export SOM in the existent file must be the most stringent in all attributes (i.e., largest size, memory residence, and most restricted access rights)."
