A_MSSQL_MAX_CHARACTERS indicates the maximum number of bytes the Acu4GL product will allow in a table row.
Microsoft SQL Server places a limit on the number of bytes per table row. The Acu4GL product adheres to this limit, but sometimes it cannot accurately count how many bytes a particular row contains (because of overhead bytes that Microsoft SQL Server adds). This variable enables the developer to set the Acu4GL product's upper bound.
You might want to try reducing it if you discover that a row cannot be added to a table. By reducing the upper bound, you may be able to prevent the problem.
If Microsoft SQL Server increases the maximum number of bytes allowed in a row (in a future release of the Microsoft SQL Server product), you can increase the value of this variable to take advantage of the new limit.
The A_MSSQL_MAX_CHARACTERS variable has a default value of "1962".
