run .sav file with -args - comp.lang.idl-pvwave

Hi All, I have created a procedure that I can execute from a window command line for example, idlde sayhello -args param1 param2 when i ran this procedure using the .sav file it didn't work, for example idl -vm = sayhello.sav -args param1 param2 It complains that the sayhello.sav function/procedure is undefined but the sayhello.sav file does exist. Please let me know if the way I execute my procedure using the .sav file is correct. Thanks!

I read other posting and realize that I can't run the .sav file with - args. Here is an example what I try to accomplish. I have a procedure that takes command line arguments as follow: pro test ; parse the parameters numArgs =3D 2 par =3D COMMAND_LINE_ARGS(COUNT=3DnumArgs) print, par[0] print, par[1] end when I ran this procedure from the dos command line using idlde by doing idlde -args hello hi and execute the test procedure it print both "hello" and "hi" I ran the idlde build project and this creates a test.sav file I need to know how I can execute idl -vm =3D test.sav from the unix and passing in the two arguments that I need. Is this task not possible? Thanks

I have used command line arguments with save files in just that way, with no problems. The pick file dialog is what IDL shows if one calls it with the -vm argument without specifying the savefile to use.

I know that window doesn't run idl but idlde so any help is appreciated. Thanks

It ran through the process that I seen when I ran it under unix. Under the unix I seen the words Hello and World printed out but not when I ran under the window environment. It didn't give any error message so I am at a lost. idlrt -vm=3Dcmd_args.sav -args Hello World

I have to use printf.

I have to use printf. Hi Ben, I have successfully executed the example above in the window environment and so I set out to build a more complicated procedures that I need to create for my work. After I build my .sav file from using idlde and ran the .sav file using idlrt -vm=3Dfilename.sav -args param1 param2 ... I get the attempt to call undefined procedure/function:'filename' message. The .sav file is in the directory. Please let me know what I did wrong. Thanks

To get the most useful help from the list, you should post the complete error message - exactly as IDL prints it. Without more info we can only guess, and my guess is that somewhere you have a variable called "filename" that you are indexing with parentheses instead of square brackets. filename(i) <-- IDL might think filename is a function filename[i] <-- an element of a variable 'filename' But, then again, you might actually have a routine called 'filename' that didn't get compiled and stuffed into the save file, but, nonetheless, gets called by the code that did make it into the save file.
