Variable repetitions

[DanBrill]

Hi,

Just getting into FM 8. Some really nice changes. I love variables, but I'm confused on one point and the documentation is of no help.

In the SetVariable dialog box there is a field for repetition. Does this mean the variable can be repeating? If so, this really makes it a very useful thing in that you can create arrays. But I can't seem to make it work this way...

Or does this refer to the repetion number of a field that you are using to set the value of the variable? If this is the case it seems like this could be accomplished with the getRepetition() function, and is a lot less useful.

Any clarity anyone can provide will be most appriciated.

Thanks,

Dan

This is explained in the help, under Set Variable script step:

"Repetition is the repetition (index) number of the variable you want to create."

Thanks. That's what it seemed to be indicating. I guess I'm doing something wrong then. For example if I create a script:

Set Variable [$$RepeatingVar ; Value: "A"]

Set Variable [$$RepeatingVar [2] ; Value: "B"]

Show Custom Dialog[

GetRepetition($$RepeatingVar;1) & ", " &

GetRepetition($$RepeatingVar;2)

]

The dialog box returns A, A. Why isn't it returning A, B?

Thanks,

Dan

GetRepetition() expects a repeating FIELD as the first argument - so I am surprised it returns anything with a variable. However, this syntax works:

$$RepeatingVar[2]

Thanks. That's what the documentation never gets around to -- how to access the data.

Yes. But I am afraid you won't find repeating variables very useful. They do not behave like repeating fields. For example, there doesn't seem to be a way to add, or multiply, 2 repeating variables in a single step.
