System variables are predefined variables which can be used in any WinTask script. Their names always begin with the character #.
System variables are used to modify the default behavior of WinTask.
System variables have a predefined type. If the type is string, the name of the system variable ends with the character $.
Some system variables are read-only: they contain values that cannot be changed by the user. For example, the system variable #ErrorMsg$ contains the error message when script execution fails.
You can change most system variables, however, simply by assigning a new value to the variable. For example, to change the current value of the #IgnoreErrors system variable, which controls Error handling, simply assign a new value:
This change will persist for the duration of the current script execution or until you make a new assignment.
