Thanks for your prompt response to my message. Unfortunately most of my code was written without consistent naming conventions. I still plan to try a few trial cases of converting part of my code as is to see what will happen if I just create and invoke FORMS with a DO FORM from within my code to give the product a Windows look and feel. To date we have had mixed results. I am looking for some materials / self study courses that could help get up the learning curve in creating classes etc. If you have any suggestions they would be appreciated. THanks. Jack.
