Re: Programs before v1r3?

Hi, Justin:

V1R3 of OS/400 added "program validation values" and "Level 40 security" (among other things), and when that paragraph you cited below most likely first appeared in the documentation. In those days, (circa 1991), those were (relatively slow) CISC IMPI AS/400s, so it took some time for the system to compute the needed program validation values, to add them to any program objects being restored from a prior release. Thus, this (now obsolete) warning notice in the documentation.

HTH,

I'm not sure if observability is the concern here. Here's a snippet from the security reference:

4. If you have any programs that were created before Version 1 Release 3, use the CHGPGM command
with the FRCCRT parameter to create validation values for those programs. At security level 40, the
system translates any program that is restored without a validation value. This can add considerable
time to the restore process. See the topic "Validation of programs being restored" on page 17 for more
information about program validation.
