Thanks Greg,
it works now. The problem was me :).
I thought the idlrt.exe is in the bin folder and I set the path to
bin. When I went through your message once again I realized that there
is one more folder bin.x86 where the file is. So, with a wrong path it
would never work. For my changeview program I was using a batch file
with the entire command and I was just executing the batch file. It
doesn't work this way with the arguments. It executed as if I am
typing changeview.sav at the command prompt. Not sure why? I have to
check the batch file issues, but thats another problem. I just typed
in the same full command at the command prompt and it worked fine
now.
Thank you all for the help.
Prashanth

Hello Greg,
I tested the program you gave and it did not work on my machine. Maybe
it is a problem with the older versions of IDL?
I will try to find a system with 7.1 and check it again.
Thank you
Prashanth

Works for me in version 7.1 on Windows...
pro test_vm_args
cla=command_line_args(count=count)
null=dialog_message([string(count),cla],/information)
end
IDL> save,/routines,file="D:\mydocs\tmp\test_vm_args.sav"
C:\Program Files\ITT\IDL71\bin\bin.x86>idlrt -vm="D:\mydocs\tmp
\test_vm_args.sav" -args "fred" "bert" "alf"
I see all three strings in the window.
regards,
Greg

You may be right. I can't get the Windows version to pick up
command arguments in the VM either. Have you talked to ITTVIS
support?
Cheers,
David

Since I am running it in VM, using print is not a good idea. I will
try to check the result by displaying in a text widget. But that is
not the point here. If it is getting into the if condition it only
means the number of input parameters is less than 3. So, I am more
worried about whats happening to my input parameters at the command
line.
Thank you,
Prashanth

Hello David,
The first part of the code goes like this
Pro ChangeView, file1,file2,file3
argsarray=command_line_args(count=nparams)
if nparams eq 3 then begin
file1=argsarray[0]
file2=argsarray[1]
file3=argsarray[2]
endif
if (nparams lt 3) then begin
file1 = DIALOG_PICKFILE(title='Select the first image')
file2 = DIALOG_PICKFILE(title='Select the second image')
file3 = DIALOG_PICKFILE(title='Select the change image')
endif
img1= read_envi_img(file1,lines=lines, samples=samples, bands=bands)
.
.
.
and I try to execute it using
idl -vm=changeview.sav -args "c:\june" "c:\october" "c:\june_oct"
This one opens the dialog window which means it is not recognizing the
input arguments. Is there something wrong with my procedure definition
"Pro changeview, file1,file2,file3" ?
Thank you

An alternative explanation is that the variables
are not set before you get to that part of the code.
That seems entirely more likely to me. :-)
The question really is, what are you *doing* with
those parameters once you pick them up with
Command_Line_Args? I'd guess, not putting them into
your variables.
Cheers,
David

I have a condition where the program calls the dialog_pickfile to
select the files when the number of parameters is less than 3. When I
execute the command with the three arguments at the command line in
DOS prompt, it still goes to the dialog_pickfile, which only means
that the parameters are not recognized.

That should work - what do you mean by "it doesn't work". What is
happening?
