Right. In that case I don't think the 'classic BASIC' Fibo program should fail, because 64-bit floats can hold integers up to about 53 bits. If it is failing I don't understand why. What's the error message?
I've not tried it, because it's got colons at the beginning of every line. Where have they come from? Typically they will break BBC BASIC:
Code: Select all
10 : IF FALSE THEN 20 : ENDIF
