Well, those who know the way Unix processes are created and executed won't have problems in understanding the problem. Still for others: Whenever a RUN command is issued the running process creates a child process in which given shell command is executed. Here **attempted** setting of environment variable will be run as a command in a newly created shell process of which the parent process (the process which issues RUN command) has no knowledge. The workaround would be to extend your 4GL and use a "C" function which will in turn call UNIX system call "int putenv(char *str)" where str is of the form "variable=value". Hope this clears the doubts. Girish ========================================================================== Standard disclaimers apply.
