#
# Name:     mcrun.sh
#
# Purpose:  Bourne shell script used to run a sequence of McIDAS commands
#           outside of a McIDAS-X session.
#
# Syntax:   mcrun.sh
#
# Notes:    Environment variables that need to be set for McIDAS commands
#           to run outside of a McIDAS-X session:
#
#             MCHOME - the home directory for the user running mcrun.sh
#
#             MCDATA - the user's McIDAS-X working directory.  NOTE: this
#                      directory should also be the first directory
#                      specified in MCPATH.
#
#             MCPATH - colon separated list of directories that contain
#                      McIDAS data files, ancillary data files, and help
#                      files
#
#             PATH -   a colon separated list of directories that
#                      Unix will search when looking for executables.
#                      NOTE: the ~mcidas/bin directory should be first in
#                      the list of directories that will be searched.
#
#             LD_LIBRARY_PATH - the search path for sharable libraries;
#                      this should be the same search path as the one
#                      used by the McIDAS session
#
#             MCBATCHFILE.BAT - the name of the McIDAS BATCH file that
#                      you want to run.
#
#           This is a Bourne shell script.  All statements must conform to
#           Bourne shell scripting syntax.
#
#           The example PATH and LD_LIBRARY_PATH definitions are set
#           for Sun Solaris.  AIX and HP-UX users need to change
#           LD_LIBRARY_PATH everywhere in this file to what is appropriate
#           on their systems
#
#             AIX:  LD_LIBRARY_PATH -> LIBPATH
#             HPUX: LD_LIBRARY_PATH -> SHLIB_PATH
#
#
# History:  20000607 - Written for Unidata McIDAS-X, -XCD 7.70
#           20040720 - Changed example display to run MAP and BAR separately

# Define macros needed for McIDAS-7.X environment
#
# MCHOME - set this to the HOME directory of the user McIDAS was installed as
# 
# MCDATA - this will be set according to who is running the script:
# 
#          user       MCDATA
#          ----------+---------------------
#          mcidas     $HOME/workdata
#          other      $HOME/mcidas/data
#
# MCPATH - this is a colon-separated list of directories McIDAS will search
#          when looking for anciallary data (e.g., map databases, enhancements,
#          stretch tables, etc.) and data (e.g., AREA, MDXX, GRID, and TEXT
#          files.
#
#          The $MCDATA directory should _always_ be the first MCPATH directory!
#
# MCLOG  - the name of the file to log output to; defaulted to
#          $MCDATA/mcrun.log
#
# MCTABLE_READ - a quoted, semi-colon-separated list of directories to search
#          for McIDAS-X DATALOCation information.  This is typically
#          MCTABLE_READ="$MCDATA/MCTABLE.TXT;$MCHOME/data/ADDESITE.TXT"
#          but can be expanded to suit the user's needs.
#
# PATH   - Unix shell search PATH with $MCHOME/bin being the first directory.
#
# LD_LIBRARY_PATH - most likely not needed, but put in for future use
