Gary,
That is the complied code of the method. The class/form designers used to have some bugs when then the VFP debugger was being used. If you went to edit a class and noticed the binary code in the method you could shutdown VFP WITHOUT saving the class and it'd be ok when you opened the class code back up. But if you saved the class without noticing the corruption you were going back to your source control to recover your class...
>Occasionally I will open or try to run a report and it will crash and cause VFP to freeze. After closing VFP via ctrl-alt-del and re-opining the report I will find corruption in the method I have code in, the method is now filled mainly with little squares and some text from I don't know where.
