Memory Reallocation

Thanks

I understand that 15C already got Build-In Matrix solver functions.
I'm curious that for the 12C Platinum it is possible to use 13 registers
with 155 program line to run Three Equations of Three Unknown program.
But with this same program is not work on 15C the problem is while input
each elements it struck at R8 and shown Error 3

Dieter explain about memory management and I still confuse about how to
set memory reallocation. So I'll look over to HP-15C Owner's Handbook.
