! Check that getarg does somethig sensible.
program getarg_1
CHARACTER*10 ARGS, ARGS2
INTEGER*4 I
INTEGER*2 I2
I = 0
CALL GETARG(I,ARGS)
! This should return the invoking command. The actual value depends
! on the OS, but a blank string is wrong no matter what.
! ??? What about deep embedded systems?
I2 = 0
CALL GETARG(I2,ARGS2)
if (args2.ne.args) call abort
if (args.eq.'') call abort
I = 1
CALL GETARG(I,ARGS)
if (args.ne.'') call abort
I = -1
CALL GETARG(I,ARGS)
if (args.ne.'') call abort
! Assume we won't have been called with more that 4 args.
I = 4
CALL GETARG(I,ARGS)
if (args.ne.'') call abort
I = 1000
CALL GETARG(I,ARGS)
if (args.ne.'') call abort
end
