On Error Resume Next

• Provide some degree of error handling by preventing program interuption from runtime error
• When error occurs, by using it the line of code containing the error is skipped over and program continues. it doesn't correct the error just ignore it without even displaying error message
• Turn off the script engine error checking: On error resume next
• Turn On the script engine to stop execution of a script when an error is encountered: on error go to 0
