The check-width mode.

Use Check Width (-checkwidth) to specify whether Progress compares CHARACTER, DECIMAL, and RAW field data against the metaschema _width field value before updating a database record. The _width field value specifies the maximum width of the data allowed in a field.

Progress allows for variable length data; SQL does not. This startup parameter lets you impose the SQL requirement that data cannot exceed the size specified in the _width field.

The valid check-width modes are:

NOTE: The _width field value for array fields is the size of all array elements after Progress converts the array element values to CHARACTER. This means that even with the -checkwidth startup parameter enabled, array fields can still surpass the _width field value.
