There's a spec in the "Guides" tab of the LC8 dictionary -- look for
"LiveCode Builder Language Reference".
I see that, but the ONLY mention it makes of lists are:
- it is one of the Types
- it holds a "sequence of values"
- what a ListExpression is.
There's also a whole LCB dictionary section in the "Dictionary" tab
that describes all the syntax relating to working with Lists.
True - but sadly there's no effective way to filter those 523 entries to
see only the ones that are relevant to a List type.
I was thinking of "proper arrays" :-) i.e. real, old-fashioned indexed
arrays - see Algol, Fortran, etc.
So we would have
read access in constant time
write access in constant time
insertion complexity - there is no such thing as insertion :-)
Yes. We're talking about the same thing. The LCB "List" datatype is
this datastructure.
I suspect we're not quite talking about the same thing - I think 'proper
lists' are something more powerful than I was picturing, but can do
everything I am looking for - and a whole lot more. If I simply ignore
all that "more", then they do what I am hoping for.
Many thanks for you patience explaining this.
I'll go start playing with LCB and try to ask harder questions :-)
Thanks
