Unlimited rights are -- defined in DFAR 252.227-7013(a)(19). By making this public release, -- the Government intends to confer upon all recipients unlimited rights -- equal to those held by the Government. These rights include rights to -- use, duplicate, release or disclose the released technical data and -- computer software in whole or in part, in any manner and for any purpose -- whatsoever, and to have or permit others to do so. -- -- DISCLAIMER -- -- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR -- DISCLOSED ARE AS IS.

Then, a new version of the first generic -- package is compiled (in a separate file, simulating -- editing and modification to the unit). Unless automatic -- recompilation is supported, this test should fail to link. -- Otherwise, the test should recompile and link the correct -- version of the instantiation and report "PASSED" at -- execution time. -- -- SPECIAL REQUIREMENTS: -- To build this test: -- 1) Compile the file LA140260 (and include the results in the -- program library). -- 2) Compile the file LA140261 (and include the results in the -- program library). -- 3) Compile the file LA140262 (and include the results in the -- program library). -- 4) Compile the file LA140263 (and include the results in the -- program library). -- 5) Attempt to build an executable image. -- 6) If an executable image results, run it. -- -- TEST FILES: -- This test consists of the following files: -- LA140260.A -- LA140261.A -- -> LA140262.AM -- LA140263.A -- -- PASS/FAIL CRITERIA: -- The test passes if a link time error message reports that -- LA140260 is missing or obsolete, or that LA14026_5 is -- missing or obsolete (optional) and no executable image -- results. The test also passes if an executable image is produced -- and reports "PASSED" (in the case where the implementation supports -- automatic recompilation). -- -- CHANGE HISTORY: -- 01 MAY 95 ACVC 1.12 LA5008W baseline version -- 06 JUL 95 SAIC Initial version -- 18 NOV 96 SAIC Modified unit names and prologue to conform -- to coding conventions. -- 07 DEC 96 SAIC Moved LA14026_3 to a separate file.
