tag!
[1/3] from: hallvard::ystad::helpinhand::com at: 25-Jan-2002 15:20
I like that tag! is a datatype.
But.
It's not a string. So certain things that may be done to strings may not be done to tags.
Still, it sometimes behaves like it's not really a datatype of its own, but, in fact,
a string.
>> a: <a href="">
== <a href="">
>> b: <a href ="">
== <a href ="">
>> a = b
== false
Shouldn't a = b return true here? In my opinion, these two tags are alike, just like
two blocks with different spacing:
>> blk1: [ 1 2 3 ]
== [1 2 3]
>> blk2: [
[ 1 2
[ 3]
== [
1 2
3]
>> blk1 = blk2
== true
Is this behaviour wanted? To what degree is tag! a datatype?

It's not a block, but it is a series, like a block and a string are...
>> a: <a href="">
== <a href="">
>> series? a
== true
And RT have decided that each character in a tag can be accessed...
>> foreach n a [print n]
a
h
r
e
f

tag! is definately a datatype. If you need a tag's contents to behave
like a block, you could use to-block...
>> c: to-block a
== [a href= ""]
but it won't give consistant results. Your other example would give
this for instance...
>> to-block <a href ="">
== [a href = ""]
HTH, anyway...

Tag is not a series datatype of type any-block but a series datatype of type
any-string. Look at the tables in Core User Guide Version 2.3 pp. 5-25 5-26.
Every string datatype has his own rules for space, but they are never ignored.

1) yes, i think
2) at all
