83	–	Even when dialect 3 quoted format parameter names are not supported, IBX still processes
84	–	parameter names case insensitive. This does result in some additional overhead
85	–	due to a call to "AnsiUpperCase". This can be avoided by undefining
86	–	"UseCaseInSensitiveParamName" below.
87	–
88	–	Note: do not define "UseCaseSensitiveParamName" when "ALLOWDIALECT3PARAMNAMES"
89	–	is defined. This will not give a useful result.
