Probably the most obvious use of a variable is to display some text that may change when a book or topic is published, such as the date published, or which user published the book. The System type variables are ideal for this. System variables can also be used in external publishing templates.
<Sys_LDate> This date is created by the <Sys_LDate> variable, which displays the date this book was published according to the computer long date format of the computer doing the publishing.
<Sys_User> This is the name of the Author-it user logged in who actually did the publishing, and is set by the <Sys_User> variable.
It should be noted that system variables are set once at the beginning of a publishing session so that all documents published in a session can have the same values when using these variables.
The system variables in this topic are shown in the variable list, however, there are additional system variables that are not shown in the variables list (Edit tab > Variables > List).
The following system variables are visible in the variable list; the variable name is added between angle brackets:
