| -- OBJECTIVE: |
| -- Check that the default attributes 'Input and 'Output work properly when |
| -- used with objects of a variety of types, including two-dimensional |
| -- arrays and records without default discriminants. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test simulates utility company service record storage, using |
| -- Stream_IO to allow the storage of heterogeneous data in a single |
| -- stream file. |
| -- |
| -- Three types of data are written to the stream file for each utility |
| -- service customer. |
| -- First, the general information on the customer is written. |
| -- This is an object of a discriminated (without default) record |
| -- type. This is followed by an integer object containing a count of |
| -- the number of service months for the customer. Finally, a |
| -- two-dimensional array object with monthly consumption information for |
| -- the customer is written to the stream. |
| -- |
| -- Objects of record types with discriminants without defaults should |
| -- have their discriminants included in the stream when using 'Output. |
| -- Likewise, discriminants should be extracted |
| -- from the stream when using 'Input. Similarly, array bounds are written |
| -- to and read from the stream when using 'Output and 'Input with array |
| -- objects. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- Applicable to all implementations that support external |
| -- Stream_IO files. |
