# Program ID: month_nn_to_mmm.sh #
# #
# Usage: MONTH_NN_TO_MMM nn #
# where nn is a month number #
# #
# Purpose: Convert nn month number to three-character month #
# abbreviation. #
# #
# Description: Echos and returns a valid three-digit month name #
# appropriate to the month number passed, or echos "" #
# and returns zero on error (zero being an invalid #
# month number). Month name returned via stdout. #
# Error messages returned vis stderr. #
# #
# Globals: No global variables assigned from this function. #
# "MN2M_" prefix identifies local function variables. #
# #
# Calls: EMAIL_MSG library function (on error). #
# #
# Exit_status: 1-12 for success #
# Zero on error. #
# #
# Notes: My biggest reason for writing this function is simply #
# to have this code/method written down somewhere. #
# #
# Modified: 2004-04-02 Bob Orlando #
# v1.8 * Expand $AWK testing and assignment. #
# #
# 2004-03-03 Bob Orlando #
# v1.7 * Change set|egrep|awk to just set|egrep. #
