Why does 1+2 goes wrong and 1+2+3 does nothing; have a look:
get "Foo, John,Westerveen 29,9751 HT,HAREN,,,,,,de Heer en Mevrouw; "
put item 1+2 of it
answer="Westerveen 29", but I expected "Foo John
put item 2+3 of it gives "Haren", also wrong, expected "John,Westerveen 29""
But asking for more items like items 2+3+4 does nothing.
Why?
item 1+2

Re: item 1+2
Hi Rob,
You need to use the & sign!
...
put item 1 of it && item 2 of it
...
&& will concatenate two strings with a SPACE between them!

because the engine will first add 1 + 3 = 3 and deliver you item 3 (1+2) of itWhy?

Re: item 1+2
Rob.
What Klaus said.
But it isn't the space that is important, it is what you wanted out of your original construction. Extracting two separate chunks from a string requires two separate chunk operations.
Imagine you had a return delimited list instead, and wanted the first and third line as a new list:
Fred
John
Harry
I bet you will see that the following is a tad wrongheaded (PseudoCode);
answer line 1 + 3
Fred
Harry
You would rather: answer line 1 & return & line 3

Re: item 1+2
Hi Klaus e.o.
Is there not an equivalent of put chars 1 to 6 of "abcdefghijklmn"
answer "abcdef"
or
get "Foo, John,Westerveen 29,9751 HT,HAREN,,,,,,de Heer en Mevrouw; "
or put items 1 to 3 of it
answer "Foo, John,Westerveen 29"
It could make scripting a bit easier....

Re: item 1+2
Hi Rob.
yes, you can:
...
put "Foo, John,Westerveen 29,9751 HT,HAREN,,,,,,de Heer en Mevrouw; " into tVar
put item 1 to 2 of tvar
## -> Foo, John
## Including the itemdelimiter, if that is what you want!

Re: item 1+2
What Klaus said again.
It is just a matter of getting used to the syntax. If you look back, you will see that simply (mentally and physically) replacing "+" with "to" is all it takes to make it all work.

Re: item 1+2
hi Klaus + Craig
Yes, changing the + to "to" is exactly I was looking for.
But where did I find that + ?: in "menus.rev" recommende by Klaus. BTW very interesting stuff all those rev's.

Re: item 1+2
Hi Rob,
you mean in the "Menus" stack from teh scripting conferences?
Where exactly is this?
I just had alook at that stack and did not find any hint about
using + for concatenating strings.
