Fortran Fortran: Execution and Input in one command line

[Aerandir90]

Hello all,

I wanted to know if there was a way to read in numerical data on the same command line on which you execute a file.

I know you can do that for i/o files like:
test.exe < file1.in > file2.out

But I wanted to know if there's some similar notation that can be used for floating point numbers.

Supposing I have this simple program that reads in 2 numbers and outputs their product.
I want to be able to do something similar to the above example in the command line:

test.exe < 3.2 87.3

Hope what I'm asking is clear enough..
I'm very new to Fortran so I'm not too sure about stuff like this
Thanks!

You can do this using the GETARG intrinsic routine. Here's a link to a page that describes how to use this function - http://gcc.gnu.org/onlinedocs/gfortran/GETARG.html.

The page above also recommends that new code be written using the newer GET_COMMAND_ARGUMENT routine that is defined by the Fortran 2003 standard.
