How to call a value from the command window to the editor window, while the value does not appear on the workspace. the value appears after using a .p code!

For example:

Editor:

A = TSystemT(B,C) % <------- this is calling the .p code called TSystemT

Command Window:

The value is 123 <---- this appears on the command window when running A = TSystemT(B,C)

Now I want to somehow import the value shown on the command window which is "123" to the Editor

like D = the value is shown on the command window

Is it really a small integer? Then simply type "123". If it is a much more complicated nested struct, please explain this. It matters, which kind of variable you want to import as code.

What about inserting this line in the function:

D = TSystemT(B,C);

The thing is that I use a p-code. and when I call it I get like many texts on the command window and nothing on the workspace except the A value which is something else:

for example when I run: A = TSystemT(B,C)

on the command window I get :

The value of M = 10

The value of N = 5

The value of S = 123

so I was looking to see if there is a way to call the S value from the command window to use it on the editor:

Do you want to do this once or frequently? For doing this once, copy&paste is the simple solution. To do this automatically, there are different options:

evalc (see Stephen's answer). Then you have to parse the output.
You can move the P-file to a specific folder and shadow the built-in functions disp and fprintf. The user-defined versions have to store the output in a persistent variable and flush it for a specific input later on, if they are called from the function. This is a very complicated way to obtain the data. It would be much easier to ask the author of the P-function to create a version with a smarter output of the results.
