Hercules & MVS
Frequently Asked Questions
As I rewrote my MVS 3.8 installation instructions, I decided to
add this page as a way of handling miscellaneous questions that might
arise. I also tried to remember and include some of the questions that
have been asked and answered in the group discussions. I will be adding to
this page, so it might be a good idea to check back from time to time,
especially if you have a question you need answered.
[December 2006] I have been made
aware of a compatibility issue when text files (scripts and JCL) from the
archives on my site are used on Linux/UNIX systems:
All your shell-Scripts/jcls and *.cnf have the Control-Character "<CTLR>M" at the end of
the line when I make a "tar -xvzf installmvs.tgz" on the ubuntu Linux-Box and then
shell-Scripts are not executable within the Shell.
Even though I create all archives using tar under Cygwin rather
than using a Windows archive program to make them as compatible as possible
between Linux/UNIX and Windows users, this is a problem that can't have a
universal solution. There is a utility that may be run on Linux/UNIX
systems - fromdos - that will translate these files so that they will function
correctly. There are a number of sources for the utility; use the search
term 'fromdos' in your favorite search engine or use this link:
