An “Async” value is treated more like a channel in DEWESoft. This means that it could be processed in a
series of calculations, like a lter. But there is no way to lter a static value. As a result of this distinction,
both async and single value numeric variables can be used within the FORMULA kind of math channel.
However, only an async value could be processed by a FILTER math channel. Do you see the differ-
ence?
Finally, you can set the default value. This eld is quite wide, which is useful when this variable will hold
some text.
Above we have created four variables - one of each basic type: text, oating number, and integer number. In
addition, there are two versions of oating numbers: one which is async and another which is a single value.
So now what can we do with these variables? Well basically, we can use them in MATH channels, and we
can also simply put them on the screen in any setup that is active when this Project is active! These values
will be stored with any data les that are created when this project is active.
Using variables in Math channels
Numeric variables can be used within your MATH channels, which is their primary purpose after all. You can
use these variables to hold constants, for example, which are needed in your calculations.
If you create a new FORMULA math channel, you will see how you can use them:
