Just a simple question about "quote()". - John P - 04-02-2018 04:09 AM
Could 'quote()' behave the same way on list's elements as "" does. What I mean when you do {a,b,c}.+"" you get {"a","b","c"} I would like to have when doing on list {a,b}.+quote() I would like to get {'a','b'}.
Thank you very much.

Hello,
What you seem to want to do is apply quote to each element of the list.
I have not tested it, but EXECON("quote(&1)", list); might do what you want.

Thank you Cirill,
I tried it in CAS history and i program and EXECON only works when the list has numerical elements as in {1,2,3}. When I wont to use a list with symbolic elements, {a,b,c}, EXECON does not work and gives me the error: "Error: Syntax Error".
Cheers

hello,
EXECON is a home command. I assumed that you were in home.
In cas, there is a similar command called zip if my memory serves me well.
But I do not know if it can do what you want as, from memory, it is designed for 2 operands operators.
apply might be worth looking at also as it might be a single operand based version of zip.

Since quote() prevents evaluation of its argument, it's not possible to use it inside a program or functional construction like in apply/map. Maybe you can quote objects in a list with the parser, but not sure...

Thank you all.
