Late Evaluation of Variables

Variables stored in file report templates must be used with one of the late evaluation operators described below. Without these operators, the variables would be evaluated as soon as the form containing them is actioned using the OK or Apply button, instead of being stored as variables in the template and evaluated when the template is run.

The three operators are:

• VTEXT, used for the late evaluation of variables when a text result is required.

• VLOGICAL, used for late evaluation when a logical result is required.

• VVALUE, used for late evaluation when a numeric result is required.

Examples of using the report variables with the late evaluation operators are given in the following sections.
