HP C Enhancements by Erryl Johnson Data and Languages Division HP C (Version A.01.21) has been enhanced with the addition of the following features. HP C OPTIMIZER HP C DETECTS UNINITIALIZED VARIABLES - With optimization level 2 enabled, the compiler issues a warning whenever it encounters an uninitialized variable. VOLATILE TYPE QUALIFIER - The volatile type qualifier directs the compiler not to perform certain optimizations on variables to which an assignment is made. HP C LIBRARIES LIBM AND LIBCRAND ARE LINKED AUTOMATICALLY - In previous versions of HP C, LIBM.LIB.SYS (math library) and LIBCRAND.LIB.SYS (random number generator library) had to be explicitly linked into the user program. This is no longer necessary. The commands CCXLLK and CCXLGO will automatically link the user program with LIBM, LIBCRAND, as well as the standard library (LIBC.LIB.SYS). For more information on all of these enhancements please refer to the updates in the HP C/XL Reference Manual (P/N 31506-60001).
