Inquiry Intrinsic Function (Specific): Returns the index of the last command-line argument. It cannot be passed as an actual argument. This function can also be specified as IARG or NUMARG.
result = IARGC( )
The result type is INTEGER(4). The result is the index of the last command-line argument, which is also the number of arguments on the command line. The command is not included in the count. For example, IARGC returns 3 for the command-line invocation of PROG1 -g -c -a.
IARGC returns a value that is 1 less than that returned by NARGS.
integer(4) no_of_arguments
no_of_arguments = IARGC ()
print *, 'total command line arguments are ', no_of_argumentsFor a command-line invocation of PROG1 -g -c -a, the program above prints:
total command line arguments are 3
