MailStream Plus - How to get the word "ORIGIN" in Field Code CSM-1167 (Entry Point - Actual / Delivery - Locale Key) in CSM Mail.dat files

all platforms
Use O in position 64 of ENT PT and/or SCF PT and/or NDC PT (and do not use an xx INF with DRPKEY or PLTKEY subkeyword)

Note: If using RP INF MDMFEP parameter for a specific origin entry zip code you can not use the xx INF
subkey words DRPKEY and PLTKEY because the MailStream Plus application will attempt to use DRPKEY and PLTKEY over RP INF MDMFEP.
