Converting Pinescript structure into Amibroker

Question

I was trying to convert a simple Pinescript condition with data structure to Amibroker AFL.

Amibroker doesn't support structures, and so I am at a loss how to write a similar logic with respect to the Pinescript code.

Any help/guidance/support help will be deeply appreciated.

type tre 
    int   bCC
    float bC8
    int   sCC

bar b = bar.new()
var tre C = tre.new()

con = b.c < b.c[4]
