Any variable that is defined on the Variables tab  can be referenced in a script. The variable’s name should be enclosed in angle brackets as in the examples below:

  if <Job: Flow Time> > 20 then ...

A variable’s value is changed only via the “Set” procedure:

  Set('my variable', 10);

Note that to assign a string value to the variable you must add quotes around the value:

  Set('my variable', '''' + 'String' + '''');

System variables, such as "Page#" should be referenced in exactly the same way:

  if <Page#> = 1 then ...

Dataset fields are referenced similar to variables except that the field name is surrounded by quotes as in:

  if <Jobs."QtyOrdered"> > 1000 then ...
