number exec(string szExecPath[, string szParameter1, ...]);
Parameters
szExecPath
the path to execute
szParameterN
the Nth argument to szExecPath
Description:
Loads and executes a new process (independent of the current one). When calling exec, a new process will be created. The control to the current process will be returned when the execution will end. This function is a little different of its C equivalent: the current process will NOT be replaced by the current one (equivalent to windows spawnl or fork + exec on penguins).
