HP-15C complex flag 9?

[HarryMJensen]

Hi Rich,
Very-very nice HP15-C tips, but I just saw that the complex mode is referred to as flag 9, to my best knowledge is it flag 8... at least on my DM15 and HP-15C CE.

Thank you for a very instructive page :-)

Hi Harry,

Thank you for taking the time to post an issue!

You are correct. Flag 8 is used to set complex mode. I use flag 9 in a couple places as a NOP (No OPeration) -- I needed a command to run that wouldn't change the stack in any way, so that's the one I picked. ;) There is probably a better way to do it, but these are my first HP-15C programs!
