How to set "Parameter T" programatically?

Hello!

I am new to logo and am trying to set any parameter T programatically for many delay blocks at once. Ideally I want to be able to set the parameter through a network connection (by reading one of the local variable memory VM slots). The help says:

> The actual value of another already-programmed function can provide the time in parameter T

Then follows a list of analog blocks and the counter. I could not get any of these to work. The only thing that did work was a workaround like this:
Activate a delay block that runs once (input wired as High) > Use the Ta output as input for multiple other delays.

The error message that it shows in the status bar is: "Recursions only allowed via outputs and flags"

Is this a bug in Logo Soft? I am using the Demo: V8.0.0.0

Thank you!
