Hi,
I suspect that the spaces you have inserted around "=" might be part of
the issue.
Here's how I run it from command line.
Minke:~ ben$ idl -vm=cmd_args.sav -args hello world
IDL Version 7.1, Mac OS X (darwin x86_64 m64). (c) 2009, ITT Visual
Information Solutions
arg[0] = hello
arg[1] = world
Here's my test routine
PRO cmd_args
par = COMMAND_LINE_ARGS(COUNT=numArgs)
IF (numArgs NE 0) THEN BEGIN
for i = 0, numArgs-1 do $
print, "arg[" + StrTrim(i,2) + "] = " + par[i]
ENDIF ELSE BEGIN
print, "No arguments passed"
ENDELSE
END
I made the SAV file this way...
IDL> .full_reset
IDL> .comp cmd_args
% Compiled module: CMD_ARGS.
IDL> SAVE, /ROUTINES, filename = "cmd_args.sav"
Cheers,
Ben
