About global variables

Last Updated : Sep 08, 2012 |

  • Some types of global variables require that you assign values. The value that you assign applies to all vector steps in which the variable is referenced, and all calls that are executing the vector steps. When you change the value, the change is reflected in all vector steps in which the variable is referenced. This rule applies to all global variable types that allow entry in the Assignment field on the Variables for Vectors screen or other methods to assign a value.

    Note:

    Some variable types allow you to use the set command, the collect digits step, an FAC or the active VDN to change the specified value. When you use any of the methods to change a variable value, the Assignment field on the Variables for Vectors screen updates to reflect the new variable value.

  • Other types of global variables use dynamic system-retrieved values for which you cannot assign specific values. This rule applies to any global variable type that does not allow entry in the Assignment field of the Variables for Vectors screen such as the tod and dow variable types.
