passwd The passwd.tar.Z file is a compressed tar file containing c source files and a man page, These TEXT files are encoded in EBCDIC so that when you unwind them on an MVS system they will be usable. I recommend the following steps: $ $ mkdir $HOME/passwd; $ cd $HOME/passwd; $ tar -xzvf $HOME/passwd.tar.Z $ make $ mv passwd $HOME/bin $ mv passwd.cat1 /usr/man/C/cat1/passwd.1 If there are any problems, let me know.
