command line args should work in the vm (at least I think it does ;^)

Of course, you can't just pass the arguments, you have to use -args
when you call idl:

idl -vm=test_sav.sav -args 5 6

Remember, also, that the args are passed as a string array(!), so your
code will fail there, too. Perhaps:

PRO test_sav

;; this might help you debug it, too:
catch, theError
if theError ne 0 then begin
catch, /CANCEL
void = error_message()
return, 0
endif

cla = command_line_args(count = count)
a = FIX(cla[0])
b = FIX(cla[1])

c = a + b
header = string(c)
file = filepath('test.txt', root_dir='d:')
OpenW, lun3, file, /Get_Lun
PrintF, lun3, header
Free_Lun, lun3

END

This program (only modified to make ROOT_DIR point to something
reasonable for me), works for me:

IDL> .compile test_sav
% Compiled module: TEST_SAV.
IDL> save, /routines, filename='test_sav.sav'
IDL> exit
Desktop$ idl -vm=test_sav.sav -args 1 2
% Program caused arithmetic error: Floating illegal operand
Desktop$ cat test.txt
12

Command line arguments should work in vm mode. For example, I do
things like:

idl -vm=test.sav -arg input_file

Something else is going on for the OP.

command line args don't work with vm mode (at least I think it doesn't)
you have to think on a different way to get your data into the routine

e.g.
env vars
an ini file can be used to build an _extra structure
( http://www.fz-juelich.de/icg/icg-1/idl_icglib/idl_source/idl _html/dbase/read_ini_dbase.pro.html)
a gui

Sorry for the half message but I hit tab and space too soon.
To conclude, I thought the problem was with command line arguments but
when I replaced a and b with simple numbers instead of the cla
arguments and executed the .sav with virtual machine nothing happend.
If I run the program in idl with compile and run, it does what is
supposed to do. What am I doing wrong here? Sorry if this is a very
stupid question, but it is the end of the week and I'm out of
options ;)

thanks in advance

thanks for the answers people!
looking back at it, the problem was that I had build the program with
IDL+ENVI, and that doesn't work with IDL VM apparantly :s
too bad
