Using the CSS Scripting Language
Special Variables
The output is:
Error in script playback line:2
>>>eco "Hello"
^
%% Invalid input detected at '^' marker.
Script Playback cancelled.
Because the script contains a spelling error, the script exits with a message telling
you what went wrong.
However, there may be cases where you want a script to continue on error. You
can override the default behavior by setting the CONTINUE_ON_ERROR
variable. When you set this variable (regardless of its value), a script continues to
execute even after it encounters syntax errors or other errors.
Exercise caution when using this variable because the CLI ignores syntax errors
Note
when the variable is set. You should set and then unset this variable in scripts
where you expect a command to fail.
For example, enter:
set CONTINUE_ON_ERROR "1"
! Spell echo incorrectly
eco "This will not print"
echo "This will print"
no set CONTINUE_ON_ERROR
The output is:
This will print
Notice in the above example that the script does not print "Script Playback
cancelled" and then terminate. This is because the CONTINUE_ON ERROR
variable is set. In most situations, it is important that you issue a no set command
on the CONTINUE_ON_ERROR variable. If you want the script to continue on
specific errors, then you have to set the variable and then unset it when you are
done. If you do not perform a no set command on the variable, then any other
syntax errors that occur in the script will not cause an early termination.
Remember, setting this variable to a value of 0 does not disable it. To disable the
variable's functionality, you must unset it.
