PilRC 2.5 Beta 3
the author of this app says:
PilRC is a Win32 program for developing USRobotics/Palm(tm) handheld applications.
The program takes a resource script file and emits one or more binary resource files, which are then included by your project's .rc, .asm or other resource file.
PilrcUI gives you a quick GUI preview of your resource file. Clicking on the client area causes it to reload.
