Array of questions

John Edmundson — Thu, 25 Jun 2026 18:56:09 GMT

My last asked question was answered with a solution so quickly, I thought I could ask another.

There should be someone who knows more of the GDL stuff than I do to tell me. When creating PARAMETERS that I want to be an ARRAY so that they can be used with MOVING HOTSPOTS, all I have found is that I have to define them in the "Parameters" tab, not in the MASTER or PARAMETER window. This means that I have to give a dimension on the array size; I am not able to have an infinite or undefined size.

Is there a way to define an array (x[][]) that can be used with Moving Hotspots that does not have a limited size? Thanks

What you're looking for is DIM

It can be used to create arrays with arbitrary dimensions

@Brucehas a series of tutorials on GDL - one of them is about Arrays. Maybe that can point you in the right direction.
