Recently I did an evaluation of Dev platforms for the PalmOS and choose CASL. It has shown to be very versitile and does not require C or Java programming. Synatactically it is familiar to VFP/VB users and should present few DataBase obstacles. It is VERY affordable at 64.96 and it will enhanced with new functionality in the next two scheduled releases. There is a wish list for developers which seems to be well monitored.
At this point I am developing a multi-keyed relational application driven by VFP tables. I am very pleased with the IDE and the compiler is fast. It produces Pcode which is VERY compact.
