Part 1 (http://www.allabouter6.com/develop/opl/opl1.php) of Ewan Spence's (FreEPOC (http://www.freepoc.org)) OPL tutorials is now available. In part 1 you are introduced to the language of OPL, given an idea of what variables and procedures are, how procedures call other procedures, and introduced to the versatile DO... UNTIL... loop structure and the essential IF...ELSE... ENDIF'. A guide to SDK and OPL development options is also available.
