onerror

Determines how errors are handled

Syntax

on error (exit|ignore)

Description

The on error statement instructs OpenDataDSL on how you want to handle errors. You have 2 options:

• exit - this is the default action which stops the currently running script and outputs the error message
• ignore - this option doesn’t stop the script running, but it places the error message into a scalar variable called error

Examples

Using on error exit:

on error exit

// Create a date variable
d = Date()

// Call an unknown method that will force throwing an error
print d.unknown()

Using on error ignore:

on error ignore

// Create a date variable
d = Date()

// Call an unknown method that will force throwing an error
print d.unknown()

// Script continues and we can see the error message in the variable called error
print error
