[REBOL] still a rookie
From: giovanni::cardona::com at: 11-Dec-2000 12:07
I finally buy the REBOL book and start reading it. As Mr. Sassenrath says,
you have to un-learn some other programming practices in order to understand
the simplicity of REBOL.
But given the fact I learned so many languages in my past 18 years, I think
I have so much to "un-learn", because there's some facts I still dont get in
order to 're-program' my programming skills (something I dont use since some
time ago, many cool authoring tools out there :)
Why I can't assign or use a value for certain operations?
I set this variable;
>> myname: [giovanni cardona iguina]
Example 1;
>> uno: 1
>> myname: skip myname -uno <-doesnt work
>> myname: skip myname -1 <-it works. but I want this on a variable
Example 2;
>> LE: length? myname
>> print myname/LE <-doesnt work
>> print myname/3 <-this path works, but I want this on a variable
Why I can use variables this way? sounds logical to me, given the fact that
REBOL claims to be so flexible, of course.
Also I noticed that if I set myname to the last value:
>> myname: last myname
and then insert a new name:
>> insert myname 'bonano
** Script Error: insert expected series argument of type: series port
bitset.
** Where: insert myname 'bonano
Then, myname loose all of the block info and the final value for myname will
be the last value
== iguina
erasing previous values, after that, you can't execute no more "back" or
skip
.
I dont know if you see this situation very usual for REBOL, but I find it
myself very weird.
Maybe Im not only looking to a problem solving, but to an understanding of
REBOL's behaviour.
