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.
