Preventing Page Breaks: PROTECT

You can specify, either in the style or in the form, that a particular paragraph should not be split in two by a page break. If this page protect attribute is set, then the complete paragraph is always printed on one page. This property applies only to that particular paragraph.

This attribute is not intended to be used to protect all paragraphs against a page break. The point is that a page break is by its very nature a dynamic event and the exact point at which it occurs depends on the current state (length and contents) of the preceding text. It is also possible that you may want to protect only certain parts of a paragraph against a page break. One way to achieve this is to use the NEW-PAGE command immediately before the text concerned starts. Explicitly beginning a new page at this point should ensure that a further page break does not occur within the text. However, this technique is not change-friendly. For example, you format your text with the help of the NEW-PAGE command so that no page breaks occur where they should not. At a later time, you insert or delete some lines. These changes cause all the subsequent text to be moved relative to the printed page, and you must check each NEW-PAGE command you previously inserted to see if it is still in the correct place.

To allow you to define the areas to be protected against a page break on an individual basis, SAPscript provides the PROTECT.. ENDPROTECT command pair. If you enclose the text to be protected in these commands, then SAPscript will ensure that each line of this text is printed together on the same page. If the complete text fits in the space remaining on the current page, then it is printed on this page just as it would be if no PROTECT command had been used. If, however, the remaining space is not sufficient for the text, then the PROTECT command has the same effect as a NEW-PAGE command and text is printed on a new page.

Thus the PROTECT/ENDPROTECT commands may be regarded as a kind of conditional NEW-PAGE command, the condition being whether or not the lines enclosed between the two commands fit in the space remaining in the current main window.



The text lines to be protected are enclosed between the two commands.
