Whoa, pardner. <grin> 

A failure to successfully convert an observable ILE program from
CISC->RISC at *FULL optimization means there is a bug, pure and
simple...   Do you know of a failure of this nature that the folks here
at IBM didn't call APARable? 

Further, recompiling from source is *not* necessary.  Sure, if the
program won't convert at *any* optimization level, there could be a
slight delay <grin> while the fix is made here in Rochester.  If the
program *will* successfully convert at a lower optimization level,
there's no need to recompile from source, period, for the following
reasons... 

Once the CISC program object makes it onto your RISC machine, a failure
to convert it to RISC does *not* destroy or delete it.  If the
CISC->RISC conversion at *FULL optimization fails for some reason, you
can still re-attempt conversion at a lower optimization level. 

Now, if you're forcing object conversion -- FRCOBJCVN(*YES) -- during a
restore and the conversion fails, the unconverted CISC object is *not*
copied onto the machine (for security reasons).  However, in this
situation you can still restore the CISC program from the media
*without* forcing conversion, and then attempt a lower-optimization
conversion on that restored CISC program object. 

Fun, huh?
