Hi,

There are several options. As mentioned by Alexandre, you can use the registry class from the FFC. You could use API calls which is a bit more tricky or the WSH which is the easiest option in my opinion:

loWSH = CREATEOBJECT("wscript.shell")
?loWSH.RegRead("HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\7.0\Options\EXACT")
?loWSH.RegWrite("HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\7.0\Options\EXACT", "ON")
?loWSH.RegWrite("HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\7.0\Options\EXACT", "OFF")
