| -- OBJECTIVE: |
| -- Check that an implementation supports the functionality defined |
| -- in Package Ada.Command_Line. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test verifies that an implementation supports the subprograms |
| -- contained in package Ada.Command_Line. Each of the subprograms |
| -- is exercised in a general sense, to ensure that it is available, |
| -- and that it provides the prescribed results in a known test |
| -- environment. Function Argument_Count must return zero, or the |
| -- number of arguments passed to the program calling it. Function |
| -- Argument is called with a parameter value one greater than the |
| -- actual number of arguments passed to the executing program, which |
| -- must result in Constraint_Error being raised. Function Command_Name |
| -- should return the name of the executing program that called it |
| -- (specifically, this test name). Function Set_Exit_Status is called |
| -- with two different parameter values, the constants Failure and |
| -- Success defined in package Ada.Command_Line. |
| -- |
| -- The setting of the variable TC_Verbose allows for some additional |
| -- output to be displayed during the running of the test as an aid in |
| -- tracing the processing flow of the test. |
| -- |
| -- APPLICABILITY CRITERIA: |
| -- This test is applicable to implementations that support the |
| -- declaration of package Command_Line as defined in the Ada Reference |
| -- manual. |
| -- An alternative declaration is allowed for package Command_Line if |
| -- different functionality is appropriate for the external execution |
| -- environment. |
| -- |

| -- CHANGE HISTORY: |
| -- 10 Jul 95 SAIC Initial prerelease version. |
| -- 02 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. |
| -- 05 AUG 98 EDS Allow Null string result to be returned from |
| -- Function Command |
