Running external application

I know I have seen it somewhere and had tried it once before but for some reason I am having a heck of time finding it. I was wondering how one would run an external application file? You know something like excel or write or word? I know at one point way back a DB engineer had wrote a small exe file that gathered some important data and we ran that from within the project, just can not remember how. THanks and have a great day.

I think you’re looking for fpmi.system.execute()
