Query: incorrect , uses obsolete func tions

Very poor. This uses obsolete functions and syntax, some obsoleted in PowerBuilder 6, many more obsoleted in PB 7. You're worse off learning it wrong. The problem is that the obsolete syntax is still supported in PB 7 , so it seems to work, but you will be using the incorrect methods and eventually when you upgrade the code may fail to work. Better off just using the Help system. There are other (numerous) errors.
