Alan, this function is an ideal candidate for a service program if you
just add one more parameter:

COPY block:

 d ChkPrtOvr       pr                  like(StdChr)
 d  InLinesRequir                 5p 0 value
 d  pInfds                         *   value

----------------------------------------------------------
Sample caller:

   fprt01    o       100       printer    infds(infds01)

    * (define the INFDS this way if you don't need it for anything else)
   d Infds01       ds          368

    ... same code as yours until subroutine

    *****************************************************************
    * srCheckOvrFlow - Check Overflow
    *****************************************************************
   c     srCheckOvrFlowbegsr

    * Check Overflow
   c                   if        ChkPrtOvr(cOverflowLimit:%addr(Infds01)) =
Yes
   c                   write     rp01_06
   c                   write     rp01_07
   c                   exsr      srPrintHeader
   c                   endif

   c                   endsr

----------------------------------------------------------
Procedure in service program:

 p ChkPrtOvr       b                   export
 d ChkPrtOvr       pr                  like(StdChr)
 d  InLinesRequir                 5p 0 value
 d  pInfds                         *   value

 d dsPrtFile       ds                  based(pInfds)
 d   ssOvrFlw01          188    189i 0
 d   ssCurLin01          367    368i 0

  *- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
  * If line number greater than overflow set for this file.
 c                   if        (ssCurLin01 + InLinesRequir)
 c                                                      > ssOvrFlw01
 c                   return    Yes
 c                   else
 c                   return    No
 c                   endif

 p ChkPrtOvr       e
