To use IDL programs in other machines

 0. make sure that path is properly set

 1. open the target program file (e.g., wmdp4.pro)

 2. from the menu, [Run] -> [Compile All]

 2.5 [Run] -> [Run wmdp4], use the program to some degree

 3. execute 
	IDL> Resolve_All
    at the bottom of IDLDE window

 4. check that there's no probelm to the output of 3.
    (if there appears too many functions, there may be a problem
     such as confusion of functions with the same name but in
     different .pro files.
     in that case, restart IDL, follow the above procedure,
     and use the program to a deeper degree in 2.5)

 5. execute 
	IDL> Save,/Routines,Filename='****.sav'

 6. transfer the above file to any machine with IDL VM
    (need to download ~100MB file to install IDL VM)

 7. in case of UNIX/Linux environment, execute
	% idl -vm='****.sav'
