50g

I have been tying to understand how to use Debug4X but I am having
trouble with my mind grasping all that is going on there. 

I remember some debugging tools built into one of the old HP
calculators that allowed you to step thru a program and see what
happens to the stack as you step through it word by word. is something
like that available on the 50G?

any help apreciated.

Best regards
gordon

Not sure about the 50g but I bet it's the same as the
49g. On 49g (and 48g) you can debug user rpl progs by
hitting the "prg" key then the "run" directory. I
don't know if the manuals for the 50g (or even the
49g) say anything about it. You may have to read the
one for the 48g.

The commands you need can be found in the run menu, the last option in 
the prg menu. Put the input data and the program on the stack and press 
DBUG. You can then single step through the program using SST or SST
(down arrow). The latter will also single step through any program 
called by the first. For a long program an alternative is to insert a 
HALT in the program where you think the problem might be. Having 
examined the stack at this point you can then KILL of CONT (rightshift 
on).

Hope this is helful

Thanks to all that help me on this issue. I had printed the manual and
have been reading it between working and it is a lot that this
calculator can do. Therre is so much to read and experiment on.
