Hi Guys

A customer has a few times now got the system error handler message "ERROR: (111) Cannot update the cursor CPX_PRODUCTS, since it is read-only." on the following replace command:

IF TYPE("cPX_PRODUCTS.Reference") = "C"
	REPLACE cPX_PRODUCTS.REFERENCE WITH ALIAS.REFERENCE
ENDIF

Now this cursor is ALWAYS created ReadWrite, and, unfortunately, in several places, in several sets of circumstances and slightly differently, in the form code, typically

SELECT cPX_PRODUCTS.*,;
	IIF(!EMPTY(cPX_PRODUCTS.CatID),cPX_PRODUCTS.CatSellPrice,0000000000.0000) as SellPrice, ;
	!EMPTY(cPX_PRODUCTS.CatID)as SellCalculated,;
	IIF(EMPTY(cPX_PRODUCTS.CatID),ThisFOrmset.SellingPriceLstInclusive,cPX_PRODUCTS.CatInclusive) as SellInclusive ;
	FROM cPX_PRODUCTS ;
	INTO CURSOR cPX_PRODUCTS READWRITE

and I can't be sure without exhaustive tracking which is used in these cases, as it's hard to predict exactly what the cust did just prior to this error.

The cust has confirmed that there is plenty of disk space.

Not my code, of course. I've rarely come across the replace construct:

Replace TableName.FieldName with ...

as used above (and frequently throughout the system).

Note also that cPX_PRODUCTS is selected from to produce the cursor cPX_PRODUCTS

Any ideas why this may happen?

'ppreciate it
