MODIFICATION HISTORY:
DATE PURPOSE BY
930111 Added "progname" variable to keep name of invoking command.
EBJ
931012 Removed altitude < 0. test to support gear development. EBJ
931214 Added various pressures (Impact, Dynamic, Static, etc.) EBJ
931215 Adopted new generic variable structure. EBJ
931218 Added command line options decoding. EBJ
940110 Changed file type of matrix file to ".m" EBJ
940513 Renamed this routine "LaRCsim.c" from "ls_main.c" EBJ
940513 Added time_stamp routine, t_stamp. EBJ
950225 Added options flag, 'i', to set I/O output rate. EBJ
950306 Added calls to ls_get_settings() and ls_put_settings() EBJ
950314 Options flag 'i' now reads IC file; 'o' is output rate EBJ
950406 Many changes: added definition of default value macros;
removed local variables term_update_hz, model_dt, endtime,
substituted sim_control_ globals for these; removed
initialization of sim_control_.tape_channels; moved optarg
to generic extern; added mod_end_time & mod_buf_size flags
and temporary buffer_time and data_rate locals to
ls_checkopts(); added additional command line switches '-s'
and '-b'; made psuedo-mandatory file names for data output
switches; considerable rewrite of logic for setting data
buffer length and interleave parameters; updated '-h' help
output message; added protection logic to calculations of
these parameters; added check of return value on first call
to ls_cockpit() so <esc> abort works from initial pause
state; added call to ls_unsync() immediately following
first ls_sync() call, if paused (to avoid alarm clock
timeout); moved call to ls_record() into non-paused
multiloop path (was filling buffer with identical data
during pause); put check of paused flag before calling sync
routine ls_pause(); and added call to exit() on termination.

$Original log: LaRCsim.c,v $
* Revision 1.4.1.7 1995/04/07 01:04:37 bjax
* Many changes made to support storage of sim options from run to run,
* as well as restructuring storage buffer sizing and some loop logic
* changes. See the modification log for details.
*
* Revision 1.4.1.6 1995/03/29 16:12:09 bjax
* Added argument to -o switch; changed run loop to pass dt=0
* if in paused mode. EBj
*
* Revision 1.4.1.5 1995/03/15 12:30:20 bjax
* Set paused flag to non-zero by default; moved 'i' I/O rate flag
* switch to 'o'; made 'i' an initial conditions file switch; added
* null string to ls_get_settings() call so that default settings
* file will be read. EBJ
*
* Revision 1.4.1.4 1995/03/08 12:31:34 bjax
* Added userid retrieval and proper termination of time & date strings.
*
* Revision 1.4.1.3 1995/03/08 12:00:21 bjax
* Moved setting of default options to ls_setdefopts from
* ls_checkopts; rearranged order of ls_get_settings() call
* to between ls_setdefopts and ls_checkopts, so command
* line options will override settings file options.
* EBJ
*
* Revision 1.4.1.2 1995/03/06 18:48:49 bjax
* Added calles to ls_get_settings() and ls_put_settings(); added
* passing of dt and init flags in ls_model(). EBJ
*
* Revision 1.4.1.1 1995/03/03 02:23:08 bjax
* Beta version for LaRCsim, version 1.4
*
* Revision 1.3.2.7 1995/02/27 20:00:21 bjax
* Rebuilt LaRCsim
*
* Revision 1.3.2.6 1995/02/25 16:52:31 bjax
* Added 'i' option to set I/O iteration rate. EBJ
*
* Revision 1.3.2.5 1995/02/06 19:33:15 bjax
* Rebuilt LaRCsim
*
* Revision 1.3.2.4 1995/02/06 19:30:30 bjax
* Oops, should really compile these before checking in. Fixed capitailzation of
* Initialize in ls_loop parameter.
*
* Revision 1.3.2.3 1995/02/06 19:25:44 bjax
* Moved main simulation loop into subroutine ls_loop. EBJ
*
* Revision 1.3.2.2 1994/05/20 21:46:45 bjax
* A little better logic on checking for option arguments.
*
* Revision 1.3.2.1 1994/05/20 19:29:51 bjax
* Added options arguments to command line.
*
* Revision 1.3.1.16 1994/05/17 15:08:45 bjax
* Corrected so that full name to directyr and file is saved
* in new global variable "fullname"; this allows symbol table
* to be extracted when in another default directory.
*
* Revision 1.3.1.15 1994/05/17 14:50:24 bjax
* Rebuilt LaRCsim
*
