command line input

[oswaler]

I need to write a program that will take input from the command line. If I have an executable named a.x the user would type something like

./a.x -a 1 2
or
./a.x -m 1 2

at the command line and then my program would put the three values in variables and use the values in the program. I've been programming for a while so I can write the program I need, I just need to know how to use the command line input.

Thanks for any help

It varies.

Which OS (eg Linux, WIndows...)
Which variant (eg 66, 77, 90, 95, 2003)
Which compiler (eg gfortran, g77, g95, silverfrost, cvf ...)

I'm writing it for Mac using fortran 95 with the absoft compiler

There are two routines: get_command and get_command_argument.

Have a look at

and
