Dear kuenze, I recommend the C.Basic interpreter, an add in. There exists a thread here:
https://community.ca...tional-release/
The last versions are at the last page of course.
I shared some programs in C.Basic which are concerned with astronomy in the widest sense (but not navigation). If you have questions, please ask.
dear piu58, thank you very much for your kind answer. i am looking for a compiler to test the casio programs before uploading them to the fx 9860. it takes so much time to debug on the calculator. i would like to try out the programs before. is there a compiler around to do that? as i understand, the basic you mention is a alternative version of cbasic on the calculator itself, which is something else. best greetings kuenze
