From the REPORT GENERATOR menu select Format Sationery > Test-print (on the text file ring menu).
You can preview the formatting of your document by running a test print (or draft version). All of the text appears as expected, while fields included on the format appears on the test print as the letter 'X' to simulate the size of the field.
The test print always requires two pages in order to show both versions of the header and trailer and to ensure that the page length and feed are correct.
Note: You cannot run a test print until the format has been compiled. If the format is incorrect and amendments are made, remember to compile the format again prior to repeating the test print.
