The subject does mention critique ;-)
FWiW: if (&EOF) is *LGL data-type, then also available:
DoWhile COND(*NOT &EOF)
CHGVAR VAR(&CLIB) VALUE(&DVSLB)
IF COND(&CLIB *NE 'NHPROD') THEN(CALLSUBR +
SUBR(EXSUBR))
RCVF RCDFMT(DVS100) OPNID(*NONE)
MONMSG MSGID(CPF0864) EXEC(CHGVAR VAR(&EOF) +
VALUE('1'))
Enddo
FWiW; if only to prevent an error on empty-file by eliminating the
/priming/ read, but also perhaps to make the code more succinct having
eliminated both that and use of (&EOF), per coding a Do-Forever with LEAVE:
Dowhile COND('1') /* do forever */
RCVF RCDFMT(DVS100) OPNID(*NONE)
MONMSG MSGID(CPF0864) EXEC( LEAVE ) /* leave on EOF */
CHGVAR VAR(&CLIB) VALUE(&DVSLB)
IF COND(&CLIB *NE 'NHPROD') +
THEN(CALLSUBR SUBR(EXSUBR))
Enddo
