If you are processing records in a primary file and you want to just skip any records that get input errors, you can code an INFSR subroutine for the file. On the ENDSR of the subroutine, code '*GETIN'. That will cause control to go to the part of the cycle that gets the next record.

Fmyfile    ip   e             disk    infsr(myinfsr)
C     myinfsr       begsr
C                   ... file error
C                   endsr     '*GETIN'


If you also want to ignore program errors encountered when processing the data in a record, code a *PSSR subroutine the same way. If you don't have any file-specific processing in your INFSR subroutine, you can use the *PSSR as the INFSR.

Fmyfile    ip   e             disk    infsr(*pssr)
C     *pssr         begsr
C                   ... general error
C                   endsr     '*GETIN'


If you don't always want to just go straight to the next record, you can soft-code the return point on the ENDSR.

Fmyfile    ip   e             disk    infsr(myinfsr)
D infsrEnd        s              6a
D recordLock      c                   1218
C     myinfsr       begsr
C                   eval      infsrEnd = '*CANCL'
C                   if        %status(myfile) = recordLock
C                   eval      infsrEnd = '*GETIN'
C                   endif
C                   endsr     infsrEnd
