Global Variables

Global Variables

EXISTS: the result of whether a specified file exists.
This is a Flow variable and it returns a boolean.

FILENAME: the name of the file processed. This is an
After variable and it returns a string.

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
Space
