Main Function and Dialog running simultaneously

Main Function and Dialog, passing variables and running simultaneously

Hi Gintaras, hi all.

I would like to run a main function and a dialog/GUI, interacting with each other.
The following code is only an example, of course, my function and dialog have hundreds of lines.

I would need a more elegant solution, preferably without global variables.
Any idea, please?

Thanks in advance and happy new year of great code!
Regards

Function Fx

Code:

type G_TEST
,int'Test
,int'Test_old
,int'Cancel
,str'sRandom

G_TEST+ t

t.Test=0
t.Test_old=0
t.Cancel=0
t.sRandom="Random"

mac "Fx_GUI"

out
rep
,if t.Cancel
,,break
,if t.Test<>t.Test_old
,,t.sRandom.RandomString(5 5 "a-z")
,,out F"{t.Test}: {t.sRandom}"
,,t.Test_old=t.Test

I would use a global variable like in your code.
Could use a local variable and pass its address, but it is dangerous, because the first thread may exit first.
In C++ could use a reference-counted variable with InterlockedIncrement/InterlockedDecrement, but in QM it is difficult.

This maybe more elegant. Waits for a kernel event object instead of for a variable.
