Find 'em, Fix 'em / Find/Fix/Data conversion and bridge programs

#### Incremental data conversion

When a logical data store consists of multiple files or databases processed according to a schedule, such as 10 billing cycles each month, data conversion often has to be synchronized with that schedule. For example, for credit-card processing, each billing cycle might be running the same programs each time but for a different client company and, therefore, with different data.

Batch-window and DASD constraints might prevent data conversion of all files or databases at once.
