This section provides a detailed reference to format codes that can be used with winio@. New features are continuously being added to ClearWin+, details of which can be found in the enhancements files on the distribution disks.
An introduction to format windows and the winio@ function is presented in Window formats. It includes general information about format strings and the form of a format code; about format modifiers, option lists, standard character strings, and help strings. It also describes the general order in which components appear in the format string and in the winio@ argument list. Please note that lowercase n and m are used to represent optional size modifiers, whilst uppercase N and M denote mandatory size modifiers (e.g. %br (Bar)).
