Несколько вопросов по МСТС

[КЕ]

Вот:

Скрытый текст:

SCRIPT T_Head_YGR

extern float block_state ();
extern float route_set ();
extern float next_sig_lr ();
extern float next_sig_mr ();
extern float def_draw_state ();
extern float state;
extern float draw_state;
extern float enabled;
extern float sig_feature ();
float next_state;
if (enabled)
{ if (route_set())
{
state = SIGASP_STOP_AND_PROCEED;
if ((enabled || !sig_feature (SIGFEAT_USER1)) && (block_state() ==# BLOCK_CLEAR))
{
next_state = next_sig_lr (SIGFN_NORMAL);
if ((next_state ==# SIGASP_STOP) || ((next_sig_mr (SIGFN_NORMAL) ==# SIGASP_STOP_AND_PROCEED) && (next_state ==# SIGASP_RESTRICTING)))
{
state = SIGASP_RESTRICTING;
}
else if ((next_state ==# SIGASP_STOP_AND_PROCEED) || (next_state ==# SIGASP_RESTRICTING))
{
state = SIGASP_APPROACH_1;
}
else
{
state = SIGASP_CLEAR_2;
}
}
draw_state = def_draw_state (state);
if (state ==# SIGASP_CLEAR_2)
{
if (next_state ==# SIGASP_APPROACH_2)
{
draw_state = 4;
}
else if ((next_state ==# SIGASP_APPROACH_3) || (next_state ==# SIGASP_CLEAR_1))
{
draw_state = 5;
}
}
}
else
{
state = SIGASP_STOP;
if (block_state() ==# BLOCK_JN_OBSTRUCTED)
{
state = SIGASP_STOP_AND_PROCEED;
}
}
} else state = SIGASP_STOP;
draw_state = def_draw_state (state);

Просто у себя не могу проверить, маршрута нет.
