JavaScript
JavaScript uses the throw statement within try to create an exception which, if not caught
using catch() , will cause the script execution to stop and the On Error tab to be triggered. See
the JavaScript errors page on W3Schools.
var s;
s = Watch.GetJobInfo(9);
if (s == "") {
throw "Value Cannot be empty";
} else {
// Do something with Job Info 9!
Watch.Log("Job Info 9's value is: " + s,4);
}
Python
In Python, the raise statement is similar to JavaScript and will stop processing unless an
except statement is used. See the python documentation.
s = Watch.GetJobInfo(9)
if not s:
raise NameError('Value cannot be empty')
else:
# Do something with Job Info 9!
Watch.Log("Job Info 9's value is: " + s,5)
Perl
In PERL, die() raises an exception and triggers the On Error tab, unless the unless command
is used. See the perl documentation.
$s = $Watch->GetJobInfo(9);
if (s = "") {
die "Value cannot be empty";
} else {
# Do something with Job Info 9!
$Watch->Log("Job Info 9's value is: " . $s,4);
}
