var %contsock = 1
set [ %link. $+ [ %contsock ] $+ .total ] just_a_sample

this make a variable :

%link.1.total just_a_sample

but i can't read it

i try like 6 types of [ ] and can't return me "just_a_sample"

echo -a %link.1.total

the problem is than the number 1 is a variable and
need [ brackets ]
