Drop the "WAIT" keyword.
Wait makes Gambas stop and wait until the process is finished.
You don't want this: you want it to run in parallel with Gambas and
read its input.

Alternatively, if you just want to get the output as a string and not
interact with the program, you can do

   Shell sCommand To someString

I find often this does what I want without getting involved in the
Process variable.
