• User customization

  The only actions needed by an user are the definition of the $XASTOP global variable, and the arrangements to make sure XAS commands are visible to the user.

• Unix users

  • make sure that the environment variable XASTOP points to the right place, placing the appropriate commands in .cshrc, .login or equivalent user login files (e.g. setenv XASTOP /dir/dir...
  • add $XASTOP/bin to the user path

• VMS users

  • include the following command in LOGIN.COM

    DEFINE $XASTOP disk:[dir.dir.]

  • make sure that, for each executable file in $XASTOP:[BIN] a foreign symbol is defined, e.g. for prog.EXE do

    prog == "$$XASTOP:[BIN]prog"

  • the above is NECESSARY if you want to call XAS programs by name (and not with RUN which does not allow argument passage)
  • you may want to automatize the above. At IFCTR private facilities exist to emulate Unix paths in VMS as part of the Real Programmers Tool

• Site-dependent customization

  Besides the configuration of xasbuild on Unix, no permanent system-level actions are needed to use XAS.
  OPTIONAL customization may occur to tailor some minor details of XAS performance, by editing or creating some files in $XASTOP/local (or $XASTOP:[LOCAL] for VMS). Refer to pre-existing XAS documentation for details.
  • the file tape.cmds contains sample definitions for the use of tapes by the fotfile program and may require customization. Additional files of similar name provide further examples.
  • the files xwfonts.list and psfonts.list located in $XASTOP/include represent the default choice of fonts for the graphic servers. They may be copied to $XASTOP/local and edited to apply site-dependent changes.
  • the same applies to psmarkers.list (which is currently unused)
  • the above graphics files may also be customized on user basis (if an user places a modified copy in his/her home directory, or even in the current working directory).
