I The field procedure parameter list communicates general information to a field procedure. I The parameter list tells what operation is to be done and allows the field procedure to signal errors. DB2 I provides storage for all parameters that are passed to the field procedure. Therefore, parameters are I passed to the field procedure by address. I When defining and using the parameters in the field procedure, care should be taken to ensure that no | more storage is referenced for a given parameter than is defined for that parameter. The parameters are I all stored in the same space and exceeding a given parameter's storage space can overwrite another I parameter's value. This, in turn, can cause the field procedure to see invalid input data or cause the value returned to the database to be invalid.
