Initializing user‑overloadable routines

%RW_INIT calls RW_INIT_METHOD before opening any files, thereby enabling you to register any of your user‑overloadable routines for use by %RW_REPORTS.


subroutine RW_INIT_METHOD
    a_status     ,n     ;RETURNED – You must set this to be 0 if there are no 
                        ; errors and to a nonzero value if there is an error.


Use RW_INIT_METHOD to initialize your user‑overloadable routines. It should call %RW_METHOD or %RPS_METHOD to register your customized routines. If any error occurs in a given %RPS_METHOD or %RW_METHOD, no further tries are made. %RW_INIT will return the error information from the routine that failed.

RW_INIT_METHOD can also include calls to UI Toolkit’s E_METHOD subroutine to overload desired Toolkit routines such as EHELP_METHOD, EFKEY_METHOD, and so on. After the return from this call, ReportWriter will register its own overloaded Toolkit routines.

RW_INIT_METHOD is also an appropriate place from which to call the Synergy DBL LOCALIZE subroutine, to apply European formatting conventions to numeric values.
