RE: [Help-glpk] Wish list - an extended "if then else" statement

Cool!  Thank you!  A bit of a kludge, but a lot better than my kludge.

Hello Marc,

This is the closest you can get with the existing syntax:

for{(time, ad) in EVENTS} {
  printf{ i in {1} : ad == "A" }
    "dual=%3g  %5d\n", ARRIVALS[time].dual, time;
  printf{ i in {1} : ad != "A" }
    "%5d dual=%3g\n", time, DEPARTURES[time].dual; }

Best regards

Xypron
