In order to run XAS as it best suits you, you shall or may need to
perform an user- or site-dependent 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
- 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
- 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
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
- 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).
