I use getarg subroutine in my FORTRAN program to call file names and related parameters from command line itself. I would like to print the whole execution command in my output file, so that the output file contains the information about what ever input file and parameters I had used to generate it. Is there a way to do that?

Hi,
You can print all the args by looping on IARGC, as an example :
PROGRAM test_getarg
INTEGER :: i
CHARACTER(len=32) :: arg
DO i = 1, iargc()
CALL getarg(i, arg)
WRITE (*,*) arg
END DO
END PROGRAM
For your purpose, just change the write statement to point to your output file.
