38	+	{ IBSQL param names in dialect 3 quoted format (e.g. :"MyParam") are by default disabled.
39	+
40	+	Dialect 3 quoted format parameter names represent a significant overhead and are of
41	+	limited value - especially for users that use only TIBSQL or TIBCustomDataset
42	+	descendents. They were previously used internally by IBX to simplify SQL generation
43	+	for TTable components in Master/Slave relationships which are linked by
44	+	Dialect 3 names. They were also generated by TStoredProc when the original
45	+	parameter names are quoted.
46	+
47	+	However, for some users they do cause a big processing overhead. The TTable/TStoredProc
48	+	code has been re-written so that they are no required by IBX internally.
49	+	The code to support quoted parameter names is now subject  to conditional compilation.
50	+	To enable support, ALLOWDIALECT3PARAMNAMES should be defined when IBX is compiled.
51	+
52	+	Hint: deleting the space between the brace and the dollar sign below
53	+
54	+	}
55	+
56	+	{ $define ALLOWDIALECT3PARAMNAMES}
57	+
58	+	{$ifndef ALLOWDIALECT3PARAMNAMES}
59	+
60	+	{ Even when dialect 3 quoted format parameter names are not supported, IBX still processes
61	+	parameter names case insensitive. This does result in some additional overhead
62	+	due to a call to "AnsiUpperCase". This can be avoided by undefining
63	+	"UseCaseSensitiveParamName" below.
64	+
65	+	Note: do not define "UseCaseSensitiveParamName" when "ALLOWDIALECT3PARAMNAMES"
66	+	is defined. This will not give a useful result.
