Re: Error in the EVAL Statement?

Jon,

you say that preceding a variable name with a sign is legal syntax - but
that begs the question:

what is produced by this syntax?  ie.  if you precede a variable with a neg
sign, will it flip the sign of the variable (pos to neg or visa versa) or
will it work like the opposite of %abs()? where it would always provide the
negative representation of the number, regardless of what it's original
sign is.

just curious...

I'm sorry but you are incorrect.  There is no such thing as continuation
characters in C specs other than to continue a literal.

In the example given as Jim has pointed out - the compiler treats it as
indicating a positive literal.  It will apparently also work this way with
a
variable name.  If however you code 3 + signs in a row you'll see an error.
Note that because spaces are not significant in expressions the + and the
literal/variable can be separated by a space/
