(HP48) Local variable limit

[Brad Barton]

Is there a limit to the number of local variables that can be declared in the 48? I'm working with some matrix operations, and I can't get it to recognize more than 9 local variables. If I put 10 numbers on the stack and try to assign them to 10 local variables, I get a "To few arguments" error. It's as if the 48 doesn't recognize the 10th value. I couldn't find an upper limit in the AUR.
