| Sys.Exec | Part of Sys module |
| Syntax | Sys.Exec ( command : string ) : boolean
|
| Description | The Sys.Exec function is used to execute an application or more often, open a data file with its associated application. Sys.Exec can be used to launch such programs as the Internet Browser by specifying a URL. Sys.Exec launches the application associated with file's suffix. (In essence, it performs the same operation as if a user double clicked on the file.)
|
| Example | This program launches an internet browser and points it to Holt Software's home page. It then launches a movie using the default video player.
if not Sys.Exec ("http://www.holtsoft.com/turing/support") then
put "The Sys.Exec call failed"
put "Error: ", Error.LastMsg
end if
if not Sys.Exec ("skate.avi") then
put "The Sys.Exec call failed"
put "Error: ", Error.LastMsg
end if
|
| Details | When the Sys.Exec procedure is used, the executing program continues execution immediately while the launched application is running.
|
| Status | Exported qualified. This means that you can only call the function by calling Sys.Exec, not by calling Exec.
