RE: LDFXxx System Tasks. -- MIDRANGE-L

O.K.  I think I understand what you're doing now.  ;-)

But I'm not sure I understand why you are restoring to RISC something you
created on RISC but saved at V3R2.  Is this a multiple AS/400 environment
with different CISC/RISC boxes?  If this is the case, I might suggest that
you do two saves, one with TGTRLS(V3R2M0) and one with TGTRLS(V3R6M0) (or
your lowest common denominator RISC OS version).  Again, it depends on how
large a restore you're talking about.  Give us a few more details if you're
not getting the answer you're looking for.

Interesting.  I just prompted SAVLIB on our V4R4 and the only valid OS
version values for TGTRLS are V3R2M0, V4R2M0, V4R3M0, & V4R4M0.  So, if
you're at V4R4 and have to restore to a V3R6 or R7 or V4R1, you may have to
put up with the program object conversion regardless.

Makes me glad I don't have to deal with different OS versions.

The programs are compiled at V3R2 and saved at V3R2 but the system
that the programs are created on is a RISC system running V4R3. The
save file exists on the same V4R3. It seems that even if the system
is RISC and you compile/save to support a CISC version of the OS, then
when the programs are restored to a RISC based system some conversion
still takes place. There does not seem anyway of avoiding this as the
LDFXxx tasks, start running during the restore. Once the restore is complete
there is no overhead (conversion) that takes place on first use of the
object.

 Vivian --
 With system value QFRCCVNRST = 0 you are telling the system not to convert
objects from CISC to RISC on the restore....... The restore will
take longer but your users will not see the hit.
