Compiler error report

The compiler objects to the continuation character in the example below, says it's not a valid character there. The truth is that the comment is not allowed there (should it be allowed there?), and the error message is wrong.

param enum F
  caption = "F"
  enum =  "a" \      ; comment
      "b"
endparam

It's fine without the comment.

param enum F
  caption = "F"
  enum =  "a" \
      "b"
endparam

Have you try this?

param enum F
caption = "F"
enum = "a" ; comment \
"b"
endparam

Then \ is part of the comment, so "b" is not one of the enum values.

Yes, after the second enum is not visible, but i think that you can't insert a comment in that way because you are inside the enum operator and the comment can be insert at the begin or at the end of the line.
i'm sorry i can't help you

Interesting, I'll find out why this happens.
