(RTFM) Or you can write the data to a flat file, and have the second program read the flat file. You have to remember if you write the variable to the environment shell, you are writing them to a new shell. Once your C code ends, the shell is gone. and the parent shell which executes your shell doesn't have the variables. -HTH Mikey -- #include <std_disclaimer.h> /* Mike Segel (MS385) */ #include <No_Spam.h> #ifdef OFFENDED_BY_CONTENT The author takes no responsibility for this post.
