A visit to the MoHPC back in Oct 2000, I found a programme for "The Castle" which I thought would be an interesting programming project to undertake.!! Unfortunately there are steps within the programme, I can understand but physically programming them into the calc appears impossible.
As I've recently purchased an i41cx for an ipad, it does make thing a lot simpler for programming, but it still does not help with the odd steps. Examples are:
Step 5 CF IND X
Step 76 FC?C IND X
Step 84 FS? IND X
I am aware that these steps are something to do with flag settings/clearing but how is that "X" added to the programming line???
