I don't think so; if this was the case when are the instructions that follow executed?

Is it a clever synthetic though? couldn’t you use the first (top) 10 keys as surrogates for 00-10 in STO and RCL and GTO?

I think a piece of the program is missing though, there aren’t routines sensitive to flag 03?
