Re: DM42 arrived today! Stack layout?

Try also reading the user manual for the HP 15C calculator, section 3 page 32 about the automatic memory stack.

With kind regards

Re: Graphics utilities: H/V lines, grids and tiles

Hello Werner

Trying to encode the program throws this error: "Invalid number format in line 01"

I found out, that it is the character, that is between the line number and the instruction that has to be deleted.

Everything is ok now. :)

With kind regards
