Some assorted HP67/97 questions

Thank you very much, Bernhard. Here are a few remarks.

- After loading a program the focus stays on the "Load program" button so that the calculator does not react on the computer keyboard. Only pressing TAB twice helps.

- The emulator now supports a data section. Great. Data is also written by the "Save program" command. But the emulator does not seem to read it back correctly. It looks like it interprets the DATA section as additional program steps so that it e.g. reports a syntax error in "line 235" which contains a 10-digit number. #-)

- The decimal point only works with a period, not with a comma. This means that e.g. on a German keyboard Num-comma does not work. You cannot enter fractional numbers using the dedicated number block on the right. I think this deserves a fix.

- SST stills seems to have some problems. Sometimes multiple lines are executed, sometimes the key produces a R/S.

- SST/BST via the cursur keys obviously were not implemented. And I admit I do not like that R/S requires a shifted [=]. I'd prefer a much easier accessible key. My favourite is the space bar.

- The display looks a bit shifted to the left. Enter a negative number and the minus sign almost touches the left display border, while even a value that uses all 15 display positions has plenty of room to the left. I think it should be shifted by about half a character to the right.

- Didn't the -x- command (substitute for the HP97 PRTX) display X for a few seconds with a flashing decimal point ?-)

- The 67/97 card reader recorded (and restored) display format, trig mode and the flag settings. Do you think a short MODE section would be feasible ?-)
