This caused incorrect initializing of the C environment for some C programs. SOLUTION: A new indicator is created in page 3 of the ECB that will be set when an exec() function is executed. This switch is tested in CLMINT to determine the correct initialization path to take depending on whether this module was started by an exec() call. This indicator also is set to the initial state by CLMINT when the exec() path is taken, so subsequent C module calls execute correctly. DEPENDENCIES SEGMENTS TO BE ASSEMBLED OR COMPILED: None.
