>What is a practical reason or application of having Resource=On in the Config.fpw for a VFP 9 application (executed by customers as .EXE file)? TIA.

From http://fox.wikis.com/wc.dll?Wiki~FoxUser

Fox User stores a variety of information, similar to the "property bag" concept of other languages. Some of these are very useful in an application, such as preventing the printing of reports from Print Preview, Hide the Print Button from the Print Preview Toolbar. It also stores:
Windows preferences and positions
Diary / Calendar data
Toolbar configurations
Most Recently Used (MRU) lists for IntelliSense

SET RESOURCE OFF if you don't need this feature in your client's runtime environment (to avoid VFP Rookie Mistakes), or toggle on and off resource files for specific functionality, like custom toolbars above.

The internal structure of the memo fields are not documented anywhere that I know of.

Use SYS(2007) to generate the checksum for a resource file entry (or make it invalid for to ignore it)
