Abstract
In a data processing system capable of responding to operator entered format parameter values the capability is provided for compactly storing directives for temporary formatting changes within text data. When temporary formatting directives are specified, the current values of the formatting parameters to be changed are stored, which enables their immediate and automatic return when the need for the temporary formatting change has passed. This is accomplished by the use of the following three new controls which are used within the text data stream: (a) the Begin Temporary Format Change, (b) the End Temporary Format Change, and (c) the Return to Previous Format. The first two of these controls are used to bracket the format change which is to take place and to identify that the format change contained therein is to be considered temporary so that the formatting states for the parameters to be changed can be remembered. The Return to Previous Format control is used to signify that the temporary format change is over and that the original formatting states whose values were stored in accordance with the Begin/End Temporary Format Change pair, are to be restored.
