This test also checks that -- Function To_Decimal produces expected results in cases where each -- of the three predefined Binary_Format constants are used in the -- function calls. In addition, the prescribed propagation of -- Conversion_Error by function To_Decimal is verified. -- -- APPLICABILITY CRITERIA: -- This test is applicable to all implementations that provide -- package Interfaces.COBOL. If an implementation provides -- package Interfaces.COBOL, this test must compile, execute, and -- report "PASSED". -- -- -- CHANGE HISTORY: -- 14 Feb 96 SAIC Initial release for 2.1. -- 30 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. -- 27 Oct 96 SAIC Incorporated reviewer comments. -- 05 JAN 98 EDS Remove incorrect subtest. --! with Report;
