Unfortunately, I don't have the SYSLOG from that IPL. The message being waited 
upon was one which said that I need to reply with an OMVS= which contained 
BPXPRMnn members which did not have any syntax errors. I knew the old PARMLIB 
BPXPRMnn suffix values and so reply with them. This allowed z/OS to continue to 
IPL. I then looked at the SYSLOG to see what I did wrong and fix it. I then 
IPL'ed again. If the BPXPRMnn syntax errors had been shown, I could have fixed 
them on another system and simply replied with same member suffixes and thus 
avoided a second IPL. OK, not a big deal. However, if I had done an "update in 
place" of the PARMLIB member, I wouldn't have had a way to continue the IPL. So 
I would have had to try to figure out the error on another system with no help. 
I guess what it really means is that I should never update an in-use member of 
PARMLIB, but copy it to a different suffix, modify it, then point to the 
modified PARMLIB member.
