subroutine  sf_constants/timestamp([unit])
Options:

unit [integer]

subroutine  sf_constants/print_date(dummy, unit)
Parameters:

  • dummy (8) [integer]

subroutine  sf_constants/stop_error(msg)

Aborts the program with nonzero exit code

The statement “stop msg” will return 0 exit code when compiled using gfortran. stop_error() uses the statement “stop 1” which returns an exit code 1 and a print statement to print the message.

call stop_error(“Invalid argument”)

Parameters:

msg [character(len=*)] – Message to print on stderr

subroutine  sf_constants/i_wait(time)
Parameters:

time [integer] – desired sleep interval [ms]

subroutine  sf_constants/r_wait(time)
Parameters:

time [real] – desired sleep interval [ms]

subroutine  sf_constants/d_wait(time)
Parameters:

time [real] – desired sleep interval [ms]
