>I created a single code program in VFoxPRo6, with the old FoxProW26 code syntax, and It worked good, but I have no clue of how to make it executable, like : alvison.prg convert it to alvison.exe, any idea?

Build project once and than build exe from it.

* Build project once
BUILD PROJECT alvison FROM alvison 
* Build exe every time you need 
BUILD EXE alvison  FROM alvison
