E05: remove line numbers from for loops

[korenmiklos]

• The output of the for-loop in Stata adds line-numbering. I suspect this to be confusing; when students try it out themselves, they may think it is part of the code. Maybe you want to consider to add another code block for the loop definition:

forvalues i = 1/5 {
    display `i'
}

instead of

. forvalues i = 1/5 {
  2.     display `i'
  3. }
