Re: Changing the ENV

robert, basically, the problem is in the run statement. executing RUN spawns a child process which inherits the parents environment. the ROBS_ENV=hello is then set and exported within that shell and control is returned to the parent process (the 4gl prog). the parent has no clue of what the child process did to the environment. you may want to write a custom runner that has a routine such as 4gl_putenv(variable,value). since it is part of the runner/4gl program, it gets around the parent/child environment problem. > > For all who are curious, how do you alter the environment while running > a 4gl program?
