looping on a specific value. You can do that by defining a repeat attribute.
You can iterate over sequences of:
- strings
- integers
- dates
- arbitrary list of dates
A sequence of integers or dates is created by specifying the
first and last element, with an optional increment (the default is one).
An ecFlow variable, whose name corresponds to the name of the repeat,
will be generated. This can be used in scripts or trigger expressions.
Repeat with day/date
The behaviour of day/date attribute under a repeat has changed from ecflow 4.0. Take the example below.
In ecflow 4.0, if task t1 took longer than 1 hour task t2 would not run.
In ecflow 5.0, once the day monday is free on family f1, its stays free until the automatic re-queue caused by the parent repeat. The net effect being that task t2 will still run, even if we have strayed into Tuesday.

Ecf Script
We will add a new task /test/f4/f5/t1.
Create new ecf script file $HOME/course/test/f4/f5/t1.ecf to use these variables.
