86	–	Even when dialect 3 quoted format parameter names are not supported, IBX still processes
87	–	parameter names case insensitive. This does result in some additional overhead
88	–	due to a call to "AnsiUpperCase". This can be avoided by undefining
89	–	"UseCaseInSensitiveParamName" below.
90	–
91	–	Note: do not define "UseCaseSensitiveParamName" when "ALLOWDIALECT3PARAMNAMES"
92	–	is defined. This will not give a useful result.
