PURPOSE: The ADDRESS CHECK option controls ACCENT R's automatic checking of valid record addresses (used with the GET statement of the PM). This command is valid in a CM, PM, SF and as a direct command.
{ENABLE; DISABLE} ADDRESS CHECK [{IF; UNLESS} clause]
|
ENABLE |
invokes automatic checking of valid record addresses. This is the default state. |
|
DISABLE |
deactivates automatic checking of valid record addresses. |
|
{IF; UNLESS} clause |
specifies certain criteria that must be met for the ENABLE or DISABLE command to take effect. |
NOTES: Previously, with ADDRESS CHECK always in effect, developers were forced to declare the data in records, get a specific record, and look in its components (fields) for the information. With the DISABLE ADDRESS CHECK option, a programmer can specifically address a byte offset that does not have to coincide with the beginning of a record. This would allow a Process Module to GET a specific byte or bytes of data from a Data Set, whether they constitute a complete record or not.
