The problem with run-time applications that use objects (of any sort) is that you have to go to special care to be sure the code is compiled. Normally with run-time applications we run the program, then type "Resolve_All" to get all the procedures and functions we need compiled, save everything as a SAVE file, and off we go. But RESOLVE_ALL doesn't resolve everything. And in particular it doesn't resolve object references. I tend to create "make" files that specially compile my object code. A make file might look like this. .Compile myNeatProgram ; My real program Resolve_All ; All the library routines, etc. .Compile trackball__define ; The trackball object. .Compile vcolorbar__define ; The vertical colorbar object. Save, /Routines, File='myNeatProgram.sav' ; The save file for run-time. Now I have a save file that will work fine in a run-time environment.
