#!F-adobe-helvetica-medium-r-normal--18* #!N #!CDarkGreen #!N #!Rall540 Missing Arguments #!N #!EC #!N #!N Any formal parameter of a module that has not had a value passed to it, either by position or by name, is initialized to the value #!F-adobe-times-bold-r-normal--18* NULL #!EF . If #!F-adobe-times-bold-r-normal--18* NULL #!EF is explicitly passed into the module, the module may still use the default value, provided it is designed to do so. The #!F-adobe-times-bold-r-normal--18* NULL #!EF value allows modules to use internal defaults for those values that are not specified in a function call. The default value must be specified in the code of the module (see IBM Visualization Data Explorer Programmer's Reference for information). #!N #!N If the function is a macro, a missing argument or an argument explicitly specified as #!F-adobe-times-bold-r-normal--18* NULL #!EF causes the default value to be used. If no default is specified, the parameter is set to #!F-adobe-times-bold-r-normal--18* NULL #!EF . #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lall541,dxall542 h Example #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
