Look here for the NMEA format and a small parsing exampleCan this be implemented in B4R?
Thank you.Look here for the NMEA format and a small parsing example

This is unlikely. However the code is B4J code. It will not work in B4R without some modifications.I think the conversion time is longer than the timer interval..
I remember the Motorola 6809 cpu had SEX in its instruction set. It meant Sign Extended. But that command disappeared in its successor the 68000. Maybe they decided to be more decent.Sexagesimal format is grade, minutes,seconds. NMEA is espressed in grade and decimal fraction.
Yes I know that and already noted SEX at that remote time was for sign extended.I'm reading that SEX has nothing to do with sexagesimal, it's Sign EXtend. Working with register sign. Sexagesimal comes from latin word SEXAGINTA which means sixty.
Thanks Erel and sorry about that.I've removed the post with the huge images. It makes the thread unreadable.

I also didn't use the MC6809 in real design, but read about it and the instructions added to the 6802, one of them was the SEX instruction (All capital)I started to study IT in 1972 the year after Intel 4004 release. In 1974 I was working in Panini's stickers company, a world wide company. I've never used assembly with 6809. Maybe binary format was unpopular so they introduced SEX instruction, a little ambiguous word.
