GETARG — Get command line arguments¶

GETARG()¶

Retrieve the POS -th argument that was passed on the command line when the containing program was invoked.

Parameters

POS – Shall be of type INTEGER and not wider than the default integer kind; POS geq 0
VALUE – Shall be of type CHARACTER and of default kind.

Returns

After GETARG returns, the VALUE argument holds the POS th command line argument. If VALUE cannot hold the argument, it is truncated to fit the length of VALUE. If there are less than POS arguments specified at the command line, VALUE will be filled with blanks. If POS = 0, VALUE is set to the name of the program (on systems that support this feature).

Standard:: GNU extension
Class:: Subroutine

Syntax:

CALL GETARG(POS, VALUE)

Example:

PROGRAM test_getarg
  INTEGER :: i
  CHARACTER(len=32) :: arg

  DO i = 1, iargc()
    CALL getarg(i, arg)
    WRITE (*,*) arg
  END DO
END PROGRAM
