As told in ML, you have some choices to get cobol compiler. One is get
free cobol compiler such as OpenCOBOL, the other is get Fujitsu cobol

programming skill is required.
To use free Fujitsu cobol, although, the download page have disappeared
and it seems to be impossible to get free anymore. If you'd rather spend
money to purchase Fujitsu cobol academic edition, see http://www.netcobol.com/order/index.htm
