Running a step by step proc

[ToutEnMasm]

Hello,
How can we stop a proc to view intermediate results ?
-There is the messagebox,she stop all the normal work of the program and isn't usable anywhere.
-A debugger do the job but with poor screen results.
- and there is this one.Program isn't stopped and screen results are what you want.There is to write them.
The sample show only the basic of work.
