RE: [MI400] Leif's MIFHASH usage (was RE: Generate hash code for a source member?)

["Dan Bale" <dbale@xxxxxxxxx>]

Leif,

Thanks for the offer.  Basically, I want to call this program giving it
parameters Library, File, & Member for input, and getting back the hash
value as a parameter.  Maybe another parameter for a Return Code / Error
MsgID.  The program SHOULD IGNORE the first 12 bytes of the source record
(the date & sequence number), and use only positions 13 through the record
length to calculate the hash.  Note that I am hoping that record length
doesn't matter; i.e., the goal is that generating identical hash values for
two source members that are identical in content but have different record
lengths.

Example call:

c        Call   'MIFHASH'
c        Parm              Library      10       input
c        Parm              File         10       input
c        Parm              Member       10       input
c        Parm              HashValue    40       output

BTW, I hope I'm not misusing the term hash here.  Am I getting back a "hash
value"?  Does CIPHER "calcuate the hash"?
