    It may need a bit better specification. For example, -123 has three figures, but four characters. What result would you like to get in this case?

    You have to write your logic in ValidateField method on that Table

    Here is the sample

    public boolean validateField(fieldId _fieldIdToCheck)
    {
       boolean ret;
    
       ret = super(_fieldIdToCheck);
    
       if (_fieldIdToCheck == fieldNum(TableName, IntegerField))
       {
           if (strlen(int2str(this.IntegerField)) > 4)
           {
               ret = checkFailed('only 4 characters or allowed');
           }
       }
    
       return ret;
    }
    

    DisplayLength Property still allow the user to enter any length of character. In form it will show only the defined display length.

    The above code will help you to validate the user entry.
