Implements (partial) functions CURSORSETPROP() AND CURSORGETPROP()

[Irwin1985]

The current behavior on the RDD side is not wired yet. That will come later with TABLEUPDATE/TABLEREVERT.

Cursor properties are stored per-workarea using the existing _WorkareaCargo container (same slot as GETFLDSTATE/SETFLDSTATE).

• CURSORSETPROP("Buffering", 1-5, [area])
• CURSORSETPROP("AutoIncError", lValue, [area])
• CURSORSETPROP("Refresh", nValue, [area])
• Unknown properties atores for forward compatibility
• nWorkArea = 0 sets session-level defaults
• CURSORGETPROP("SourceType") returns 3 (table)
• CURSORGETPROP("SourceName") returns DBF full path
• CURSORGETPROP("Database"), "SQL", "ConnectHandle", etc. returns sensible defaults

I used the CursorProperty enum from XSharp.Core.RDD for property lookup instead of String.Compare.

Irwin, Please look at src\Runtime\XSharp.Core\RDD\CursorProperties.prg
This file already has an enum for the cursorproperties and a function to translate the string to the number.
And instead of hardcoding the dictionary, I am using the Enum.GetValues() and Enum.GetName() methods
I would also use the Enum for the default values and not the string
Finally, instead of the long list of IF ... statements I would cast the long to the enum and then use a SWITCH statement. That is easier to read and slightly faster.
On the other locations I would also cast nProp to the CursorProperty enum once, so you do not need to use an (LONG) cast in all comparisons.

Hi Robert,

Done. Switched to the CursorProperty enum.

Thanks.

Great
I am just building the next RC1 installer. This will not be included yet.
