I don't agree, given the complexity of z/OS data management,
that an I/O error on an input data set is unlikely to the
orders of magnitude you suggest. And for "the developer to
handle" the condition is merely to employ the intrinsic OS
facilities to provide a lucid report. For comparison, injecting
similar errors:
In HLASM:
1
PAGE 1
HIGH LEVEL ASSEMBLER - INTERRUPT AND DIAGNOSTIC DUMP
HLASM R5.0 2009/02/13 15.31
0** ASMA999U Assembly terminated - SYNAD Exit taken - Permanent I/O error on
SYSIN data set
,SPPGASM ,ASSEMBLE,JES ,I,SYSIN ,GET ,WRONG LEN
RECRD,**************,QSAM
And in IEBGENER:
1DATA SET UTILITY - GENERATE
PAGE 0001
-IEB352I WARNING: ONE OR MORE OF THE OUTPUT DCB PARMS COPIED FROM INPUT
IEB351I I/O ERROR ,SPPGGENR,TST001 ,OMVS,*,SYSUT1 ,READ ,WRONG LEN

Apparently. I suspect the HLASM and IEBGENER messages
embed SYNADAF results.
