Variable Text

Variable text is text that can include a series of codes that tells the program to include not a fixed piece of information, but instead a certain kind of information about a picture—its output can “vary.” You can mix ordinary these codes freely within variable text. The program evaluates the codes, examines the picture’s picture information, and fills in the relevant text. Each code must precisely match the writing instructions and must be enclosed in {curly braces}.

The specific writing instructions are always available  via the small button with the triangle symbol next to the line with the variable text.
