• The datahandler, and the datahandler argument, should not be declared in an ESQL declare section. Therefore do not use a colon before the datahandler or its argument.

• You must ensure that the datahandler argument is a valid Fortran variable address. ESQL will not do any syntax or datatype checking of the argument.

• The datahandler must be declared to return an integer. However, the actual return value will be ignored.
