Export/import programming to/from a file

You can export all of your programming in a Sesame database form to a standard text
file for review or editing with any text editor. These features are available on the File
menu of the Program Editor. With some programming already in the form, select
File/Export All to Text File. The Program Editor will display a Programming File dialog
box. Name the file, adding the “.pgm” extension, and click OK.
The file that is saved is a plain text file. When editing the file outside of Sesame, it is
important that you do not modify the heading line for each programming function:
** PROGRAMMING SECTION: [INVOICE #] [On Element Change] **
If @IsBlank(Invoice #)
{
Invoice # = @Number
}
These are the lines that start and end with **. They are the keys that tell Sesame
where to place the programming when you import the file.
Importing is done the same as exporting. From the Program Editor's File Menu, select
File/Import from text file. The same dialog will display showing all files with a “.pgm”
extension. If you gave your file a different extension, drop down the Show window and
change it to display All Files.

Note: When you import a file into to the Program Editor, any element listed in the
imported file will overwrite any programming for that element in the editor. Any
existing programming in an element/event programming slot in the editor which is not
addressed in the imported file will remain unchanged.

olddog,  I just tried this procedure again this morning and it dumped the entire app. which was several pages, without trouble.

My procedure is:

From Program Editor:

File
Export all to text file
Give it a name in "File Name" at the bottom
Click Ok

Sorry olddog it looks like I didn't look close enough at this.

And I thought I was starting to catch on!

Thanks for the correction Erika.
