4GL -checkwidth startup parameter

Progress 4GL programmers can override Data Dictionary column definitions in 4GL programs. However, a SQL application cannot read a record if a column contains data greater than the SQL _width value defined in the Data Dictionary. When the SQL engine attempts to retrieve a column that exceeds the metaschema _width field definition, an error message is generated and the attempt to access the record fails.

Use the -checkwidth startup parameter to specify whether the Progress 4GL client 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.

The syntax for the -checkwidth startup parameter is:

Syntax

The -checkwidth startup parameter can be employed in the following modes:
