UNIX tips

Here are some helpful tips when working with a UNIX®-based operating system such as Linux™ or Mac OS X®.

The Z390 environment variable

By default, all of the Perl scripts supplied as bridges to the Microsoft Windows® batch files look in this variable before looking at directories in the following search order:

  • $Z390
  • $HOME/lib/z390
  • /usr/local/lib/z390
  • /usr/lib/z390

You can add the following statements to the appropriate .profile login script:

Z390="~/z390"  # Or wherever you've installed it
export Z390    # Makes it permanent

Note that [enhancements:#110] will make changes to this order, including inserting the current directory in the second position.
