ARGS
Command Line Argument Retrieval


ARGS is a FORTRAN90 program which demonstrates command line argument retrieval.

In particular, ARGS is a demonstration of the IARGC and GETARG routines, commonly available on UNIX systems.

These routines allow a FORTRAN program to count and retrieve the command line arguments with which it was invoked. Thus, if an executable program is called fu and we invoke it with the command

fu man chu
then IARGC will return the value 2, and GETARG, with an input of 0, 1 or 2, will return the values fu, man or chu.
