func1 := proc(system1)
for i from 1 to 100 do
func1([diff(y,t) = data[i+t+1], diff(x,t) = data[i+t+1]])
i is depend on the for loop inside a function, but woud like to pass this system into a function with i
this will cause error
how to write better for passing a system as parameter using variable inside a function?
