Hey, I tried like twelve variations of this and still get weird results. Can
anyone tell me what I am doing wrong, and why the output seems to defy reason?
What I had in mind was a function that took as it's parameters some text to
enclose within tags, and the information needed to build a tag around the text.
The sample list tries to supply all of the information needed to create a valid
HTML "anchor" tag.
Now, I realize that the end tag does not have a "/" in it, that is minor at
this point. What really concerns me is how the string "REBOL Web" keeps getting
into the output at the wrong spot. I inserted 'print statements after each
assignment to see what data was being dealt with, and I cannot find out how
s-tag is reading "REBOL Web" from a series that no longer has that string as a
member.
The obvious answer is that it DOES have that string as a member, but if that
were the case ... then what is the point of: "series: next series" which is
taken right from the examples of the new users guide?
I'd also like to note, for the record, that REBOL is _not_ that easy to learn.
I can program quite well in various BASIC's, PERL, JavaScript, C++, DCL (DEC
Command Language), and various batch & shell scripts - yet I am having a
dickens of a time learning REBOL! Maybe it would be much easier on me if REBOL
were my first language ...
