I have a requirement to generate CHECKSUM for MF objects.
I have been trying with AMASPZAP but it is doing the checksum on the sysin how do I get it to checksum the object itself?
the SAS tool OBJZAP seems to be what I am looking for but we do not have it installed at this siite.
I sent IBM an email and got a response which is not good.
anyone able to assist. |

what is the objective ??
what kind of checksum, what objects, environment ( zOS/USS ) ,
checksum is a bit generic ..
simple checksum as amaspzap
or a bit more sophisticated as a crc or a signature |

objective is to generate a checksum for an object (program) and be able to compare this to anoher load library (generate the checksum also) and see if they are the same hence is the same version of the program being loaded into the correct cics region during migration.
I said ZOS environment.
Amaspzap is simple it does not seem to be simple to drive.
no signature required. |

binder object I suppose ( You should have added the adjective in Your first post )
not even OBJZAP will be useful,
all the CHECKSUM would be made for.. a single csect,
so You would have to find out all the csects in Your object.
You are going to have a good time writing a program to do it
but why reinvent the wheel
use supercE specifying compare type file
it uses a hashsum algorithm
and again all depends on how You transport/move/copy/rebuild Your &OBJECTS across the libraries,
if You rebuild any approach will fail ( timestamps ) whatever tool |
