  MovVal ST(0), Input$("\nConsumption: ", "500")               ; ask e.g. for cubic metres of water
  movaps xmm1, TimeSF(Input$("older date: ", fDate$(-30)))     ; suggest thirty days before today
  psubq TimeSF(Input$("newer date: ", fDate$())), xmm1         ; subtract from today
  FpuPush TimeDiff(d)
  Print Str$("%i days between the two dates\n", ST(0))         ; display difference in days
  fdiv
  Inkey Str$("Consumption per day: %3f units", ST(0)v)         ; calculate consumption per day
EndOfCode

The strings "500", fDate$(-30) and fDate$() are suggestions and can be edited by the user with the arrow and backspace keys. The consumption can be any number, e.g. 1.5; the dates must be entered in the correct format dd.mm.yyyy - sorry, U.S. format won't work

Example:

Code: [Select]

Consumption: 500
older date: 29.01.2022
newer date: 29.05.2022
120 days between the two dates
Consumption per day: 4.17 units
