#  Program:    numpager
#  Author:     Mark J. McDonagh
#  Version:    1.1

#
#  Description:
#
#    This script allows users to send a numeric page to a pre-defined
#  group of people based on a lookup table of names and pager numbers.
#
#    This script was primarily written as a system monitoring tool, but
#  can also be used as an automated way to page users, systems staff,
#  sales staff, etc.
#
#    The script looks for 2 parameters, 1st the name of the person that
#  the page is being sent to and 2nd the numeric messagewhether it is an
#  error code from a script the system is monitoring or if it is a phone
#  number of the person placing the page so that the recipient can call
#  them back.
#
#  Files: .UNIX_ONCALL   name of person handling UNIX problems
#         .PC_ONCALL     name of person handling PC problems
#         .PAGER_LIST    list of names and pager numbers (seperate by
#                        tabs)
#
#  Variables:  UNIXSA    use as 1st parameter to page UNIX Administrator
#              PCSA      use as 1st parameter to page PC Administrator
#
#  Example:    numpager UNIXSA 001
#
#         This would call the UNIX on call person and display 001 as
#         the error code on his/her pager.
#
#  Example:    numpager mark 5551212
#
#         This would call mark and display 5551212 as
#         the phone number to call on his pager.
