Question How to check index of a array element in shell script?

Example - Script to find the index of a month from array

Code:
MONTHS="Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec"
set -A MON $MONTHS
A="Sun May 23 09:34:30 GMT 2010"
getMonth=`echo $A|cut -c5-7`  ##getMonth=May
Arrayindex_in_MONTHS_array= ????        # { 0,1,2,3,4 } - at fifth place

Output should come 4 => $Arrayindex_in_MONTHS_array

Thanks,
kuldeep
