Custom-conversion functions

Custom-conversion functions allow you to add additional data conversion capability to the . This feature lets onpload call a custom-conversion function during the data-conversion process.

When you create a custom-conversion function, you associate it with a particular mapping of input field to output field. To associate a custom function with a field, enter the name of the function in the Function text box of the Mapping Options window. For information about mapping options, see Mapping options.

Although the mapping options associate the custom-conversion function with a particular field, the function can access all the input data fields and all the output data fields through a set of API functions provided with the onpload utility.
