Parsing numbers accurately is tricky, since there are so many different formats (leading minus sign, decimal point, exponent etc.). LBB's syntax coloring uses simple rules that can't easily be extended to numbers.

Unfortunately coloring numbers differently won't always solve this problem. Consider these two variable names:
Code:
The first is ba followed by the number eleven and the second is the word ball but they are almost identical, even to somebody with good eyesight! Because neither of them is a number they would not be colored differently even if LBB supported that feature, and they are not colored differently either in LB 4 or in Liberty BASIC Workshop.
So you could try using LBW (it interfaces very nicely with LBB; there are instructions here) but syntax coloring is not a complete solution to the problem.

Although I have been using LBB for quite a long time now, I have only just discovered that the syntax colouring problem manifests itself in the same way when LBB is run with linux/wine. My language setting is English-UK and many fonts tried. My programs do not contain any foreign characters. Whether that helps or not I don't know, but I am not expecting a solution - I can live without colouring as I obviously have done for some time! Just thought I would add to the gathered knowledge.

You refer to "the syntax colouring problem" as if it is something well-known and common, but the 'problem' discussed in the earlier posts of this thread manifests only in very rare circumstances, as I have explained. I should perhaps delete those posts in which the issue was misunderstood and misrepresented.
To reiterate, it occurs only when Windows performs a 'font substitution', which can happen when your program contains a character that is not available in the currently selected font. You can often avoid it altogether by selecting a font with a wide coverage of Unicode glyphs (don't choose 'FixedSys' which is particularly poor in this respect; note the reference to 'FixedSys Excelsior' as a possible alternative).
There is nothing I can do about the rare occasions when it does misbehave, because the Rich Edit control does not notify the host program that a font substitution has taken place.
Syntax coloring works perfectly for me, and for most other users as far as I know.
Richard.
