TrySystem() — Tries to execute an operating system command
TrySystem(command)
Attempts to execute a command in the
underlying operating system. The result of the
command will be placed in the
SYSTEMSTATUS channel variable and will be one of the
following:
The specified command could not
be executed.
The specified command executed
successfully.
The specified command executed,
but returned an error code.
This application is very similar to the System() application, except that it always
returns normally, whereas the System() application will return abnormally if
it is unable to execute the system command.
