After all instructions are typed in, we press the “enter” key to execute the sequence. Individual instructions in the code can be assignment statements, iteration statements (loops), conditional (if), input or output statements, functions, or other programming constructs.

"Web1. @Numth @Calle @whuber: Mathematica make the summation index local using Block. In this way k has a local value for the Sum function. However, k is still k so that g [k-1] translates into Sum [Binomial [k-1,k], {k,0,k-1}] which will evaluate to 0 (because Binomial [k-1,k]=0).
