Where are the C header files located? Isn't it > SYS$COMMON ? Well, sort of. Use SYS$LIBRARY instead, though. SYS$LIBRARY is a search list composed of SYS$SYSROOT:[SYSLIB] and SYS$COMMON:[SYSLIB] (that's were the "sort of" comes in). SYS$COMMON is a logical that points to a set of directories common to all satellite nodes in a cluster with a common system disk. SYS$SYSROOT is a logical that points to a set of directories that are specific to each satellite node in a cluster with a common system disk. Also, the command: HELP CC RUN-TIME_FUNCTIONS (or just HELP CC RUN) can be used to locate functions. This will also tell you the header file that's required. -- Kent Covert, Software Coordinator Miami Computing and Information Services Miami University, Oxford, OH [log in to unmask] (internet) kacovert@miavx1 (bitnet)
