MachineLogic - No project on the PLC.

There is a size issue on the MachineLogic side. The MachineLogic code you write has to live in the 640K boundaries restricted by DOS. Along with MachineLogic, DOS, Interact, Command.com, Himem.sys, touch screen drivers, Networking drivers and BIOS TSRs have to live there. With all of these programs restricted to the 640K the more you take for programming the less you have for these other programs. Your program just got to the limit of the original RTXDOS. We increased it by 15K. This will allow more programming room and online debugging room.
