How to Implement a While Loop

Answered

In my model, I need to implement a pulsing event which occurs on regular basis while a given condition is true.

I have used the following, but the pulse only happens once, instead of several times.  This is strange because the condition remains true, so I would expect my pulse to just keep on pulsing.

if ("Cash Reserves" < 10000)

then

pulse(
("Amount of Assessment",
start="time",
interval="Frequency of Assessment"
)

else

0

Does anyone know what I'm doing wrong?

  Found the problem...

  I was using "time" rather than "start_time"

  Glad you've found the issue! Note that your formula above seemed to have a few syntax errors, maybe just from putting in here, but here's a standalone example of using a pulse inside a conditional in case it's helpful for others. We'll look at adding more examples into the functions and syntax documentation.

  if "time" > 10 and "time" < 30
  then pulse(10, "start_time", 2)
  else 0
