No computer software is perfect and occasionally your data files get corrupted either by the operating system or by the application software that you use to create and maintain the file. Files created with Pagemaker are no exception, the difference is that Pagemaker contains a facility within the program itself that can fix many of the corruptions to your Pagemaker files.
Signs that your Pagemaker file may be corrupted include:
In most of these cases the content may display perfectly when displayed in the story editor but looks different when you look at the page layout. If this is what you see then your file is most likely corrupt. You will need to use Pagemaker's Recomposition function to attempt to repair the file.
The first thing that you need to do if you suspect that your file is corrupt is to save a copy of the file just in case attempting to fix the file makes things worse.
Pagemaker's recomposition option can't be found in any of the menus that appear at the top of the screen. This is one of those hidden options that provides a useful service but which you don't need to use every day. By hiding the option you are protected from running it accidentally by selecting the wrong option from the menu.
To run the recomposition facility you must first have the pointer tool selected and not have any part of your document selected. You also need to be in page layout view and not in the story editor.
To run recomposition you need to hold down both the Shift and Ctrl keys on your keyboard and then select Hyphenation from the Type menu. This will start the recomposition process. Once the process completes (which may take some time with a big document) your computer will beep. The number of beeps tells you the outcome of the recomposition process. One beep indicates that Pagemaker didn't find any problems that needed fixing. Two beeps indicates that Pagemaker found problems and repaired them. Three beeps indicates that Pagemaker found problems but was unable to repair them.
If Pagemaker does manage to fix your corrupted file then the first thing you will want to do is to save the fixed file so that you don't end up losing it and having to repeat this process.
Sometimes the "repairs" that Pagemaker makes to your file may just make things worse (it is not always possible for it to work out how to correctly fix a corrupted file). In this case you can recover your "unfixed" version by selecting Revert from the File menu. Other things that you might try if Pagemaker is unable to fix your file using the recomposition facility is to use Save As to force the file to be saved in its entirety (normally Pagemaker just saves the alterations to your file to the end of the existing file content).
