42	+	{ IBSQL param names in dialect 3 quoted format (e.g. :"MyParam") are by default disabled.
43	+
44	+	Dialect 3 quoted format parameter names represent a significant overhead and are of
45	+	limited value - especially for users that use only TIBSQL or TIBCustomDataset
46	+	descendents. They were previously used internally by IBX to simplify SQL generation
47	+	for TTable components in Master/Slave relationships which are linked by
48	+	Dialect 3 names. They were also generated by TStoredProc when the original
49	+	parameter names are quoted.
50	+
51	+	However, for some users they do cause a big processing overhead. The TTable/TStoredProc
52	+	code has been re-written so that they are no required by IBX internally.
53	+	The code to support quoted parameter names is now subject  to conditional compilation.
54	+	To enable support, ALLOWDIALECT3PARAMNAMES should be defined when IBX is compiled.
55	+
56	+	Hint: deleting the space between the brace and the dollar sign below
57	+
58	+	}
59	+
60	+	{ $define ALLOWDIALECT3PARAMNAMES}
61	+
62	+	{$ifndef ALLOWDIALECT3PARAMNAMES}
63	+
64	+	{ Even when dialect 3 quoted format parameter names are not supported, IBX still processes
65	+	parameter names case insensitive. This does result in some additional overhead
66	+	due to a call to "AnsiUpperCase". This can be avoided by undefining
67	+	"UseCaseSensitiveParamName" below.
68	+
69	+	Note: do not define "UseCaseSensitiveParamName" when "ALLOWDIALECT3PARAMNAMES"
70	+	is defined. This will not give a useful result.
