The code example you've provided will work, but the trouble is that you need
to define the same prototype multiple times, so change management becomes an
issue. What LIKEPR would give us is the following


Source member: CUGLS001PR (Prototypes for service pgm CUGLS001)

D CUGLS001_getPeriodStatus...
D                 pr              10a
D  iCompany                                      like(t_Company)
D  iPeriod                               like(t_fiscalPeriod)
D  iSubledger                              like(t_ledgerCode)
options(*nopass)


Source member: CUGLE001 (Some pgm that uses CUGLS001)

/copy CUGLS001PR

 // define alias names for srvpgm procedures
D getStatus        pr                    extproc('CUGLS001_GETPERIODSTATUS')
D                                      likepr(*EXTPROC)


That's essentially what I was hoping to achieve.
