Find makelist in the LIST->MATH toolbox menu, select it, press help. This is what is shown.

Quote:Syntax: MAKELIST(expression, variable, begin, end, [increment])

Make List. Calculates a sequence of elements for a new list. Evaluates expression, incrementing variable from begin to end values, using increment steps (default 1). The MAKELIST function generates a series by automatically producing a list from the repeated evaluation of an expression.

Example: MAKELIST(2*X-1, X, 1, 5, 1) returns {1, 3, 5, 7, 9}

Using that, MAKELIST(A,A,1,4) will do what you have indicated.

I had sometime to explore MAKELIST. In CAS, the command MAKELIST(e^{2*k*pi*i}, k,1,5) produces an empty list [[]]. In HOME it works, provided X replaces k.
Why is it? What am I misinterpreting?

Thank you
