ARGS
Command Line Argument Retrieval

ARGS is an executable FORTRAN77 program that 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
