35 FUNCTION: Top level routine for LaRCSIM. Includes
36 global variable declarations.

46 ----------------------------------------------------------------------------
54 ----------------------------------------------------------------------------
60 930111 Added "progname" variable to keep name of invoking command.
62 931012 Removed altitude < 0. test to support gear development. EBJ
63 931214 Added various pressures (Impact, Dynamic, Static, etc.) EBJ
64 931215 Adopted new generic variable structure. EBJ
65 931218 Added command line options decoding. EBJ
66 940110 Changed file type of matrix file to ".m" EBJ
67 940513 Renamed this routine "LaRCsim.c" from "ls_main.c" EBJ
68 940513 Added time_stamp routine, t_stamp. EBJ
69 950225 Added options flag, 'i', to set I/O output rate. EBJ
70 950306 Added calls to ls_get_settings() and ls_put_settings() EBJ
71 950314 Options flag 'i' now reads IC file; 'o' is output rate EBJ
72 950406 Many changes: added definition of default value macros;
73 removed local variables term_update_hz, model_dt, endtime,
74 substituted sim_control_ globals for these; removed
75 initialization of sim_control_.tape_channels; moved optarg
76 to generic extern; added mod_end_time & mod_buf_size flags
77 and temporary buffer_time and data_rate locals to
78 ls_checkopts(); added additional command line switches '-s'
79 and '-b'; made psuedo-mandatory file names for data output
80 switches; considerable rewrite of logic for setting data
81 buffer length and interleave parameters; updated '-h' help
82 output message; added protection logic to calculations of
83 these parameters; added check of return value on first call
84 to ls_cockpit() so <esc> abort works from initial pause
85 state; added call to ls_unsync() immediately following
86 first ls_sync() call, if paused (to avoid alarm clock
87 timeout); moved call to ls_record() into non-paused
88 multiloop path (was filling buffer with identical data
89 during pause); put check of paused flag before calling sync
90 routine ls_pause(); and added call to exit() on termination.
94 $Original log: LaRCsim.c,v $
95 * Revision 1.4.1.7 1995/04/07 01:04:37 bjax
96 * Many changes made to support storage of sim options from run to run,
97 * as well as restructuring storage buffer sizing and some loop logic
98 * changes. See the modification log for details.
100 * Revision 1.4.1.6 1995/03/29 16:12:09 bjax
101 * Added argument to -o switch; changed run loop to pass dt=0
102 * if in paused mode. EBj
104 * Revision 1.4.1.5 1995/03/15 12:30:20 bjax
105 * Set paused flag to non-zero by default; moved 'i' I/O rate flag
106 * switch to 'o'; made 'i' an initial conditions file switch; added
107 * null string to ls_get_settings() call so that default settings
108 * file will be read. EBJ
110 * Revision 1.4.1.4 1995/03/08 12:31:34 bjax
111 * Added userid retrieval and proper termination of time & date strings.
113 * Revision 1.4.1.3 1995/03/08 12:00:21 bjax
114 * Moved setting of default options to ls_setdefopts from
115 * ls_checkopts; rearranged order of ls_get_settings() call
116 * to between ls_setdefopts and ls_checkopts, so command
117 * line options will override settings file options.
120 * Revision 1.4.1.2 1995/03/06 18:48:49 bjax
121 * Added calles to ls_get_settings() and ls_put_settings(); added
122 * passing of dt and init flags in ls_model(). EBJ
124 * Revision 1.4.1.1 1995/03/03 02:23:08 bjax
125 * Beta version for LaRCsim, version 1.4
127 * Revision 1.3.2.7 1995/02/27 20:00:21 bjax
130 * Revision 1.3.2.6 1995/02/25 16:52:31 bjax
131 * Added 'i' option to set I/O iteration rate. EBJ
133 * Revision 1.3.2.5 1995/02/06 19:33:15 bjax
136 * Revision 1.3.2.4 1995/02/06 19:30:30 bjax
137 * Oops, should really compile these before checking in. Fixed capitailzation of
138 * Initialize in ls_loop parameter.
140 * Revision 1.3.2.3 1995/02/06 19:25:44 bjax
141 * Moved main simulation loop into subroutine ls_loop. EBJ
143 * Revision 1.3.2.2 1994/05/20 21:46:45 bjax
144 * A little better logic on checking for option arguments.
146 * Revision 1.3.2.1 1994/05/20 19:29:51 bjax
147 * Added options arguments to command line.
149 * Revision 1.3.1.16 1994/05/17 15:08:45 bjax
150 * Corrected so that full name to directyr and file is saved
151 * in new global variable "fullname"; this allows symbol table
152 * to be extracted when in another default directory.
154 * Revision 1.3.1.15 1994/05/17 14:50:24 bjax
157 * Revision 1.3.1.14 1994/05/17 14:50:23 bjax
