Consider this:

Instead of
I typed
(I added the capitalization of AAdd, X# doesn't do that unfortunately)

If I make the same mistake in VO, I get 2 clear errors on the same line so I know immediately what I've done wrong:
entity AERROR is unknown: 51121
bad function call: 51138

In X# I get:
Error XS9002 Parser: unexpected CRLF, are you missing a token ?

so I've no idea what is actually wrong.

Would it be possible to improve compiler errors more towards the level we are used to in VO?

Hi Dick,

Yes, it's on the list to improve such error messages. The difference between VO and X# is that VO uses a hand written parser, while X# uses a rules based one. The disadvantage of VO's one is that in a lot of cases it allows to compile things that should not be allowed to compile in the first place and do not make sense. The main disadvantage of X#'s one is exactly that, it's not easy to make it report good enough parser error messages. But Robert and Nikos are working on that.

Hello Chris,

Good to know. It's probably not the most urgent thing to do but gradually closing the gap between VO and X# on the whole is important.

I can imagine that a tighter compiler is more important than clear errors, but unfortunately unhelpful errors are more visible for a programmer than absent compiler errors which should have been there. :unsure:

DIck

Yeah, agreed with that!
