*+ 072712 I3 families,tables(curves,functions),mrf,mrfd,c453...

So called families are 'curves' to control RF.
The first one is anode curve dealt in module hv.cpp.
The other 8 curves (#1:8) are so called high level RF curves, dealt in hl.cpp
PGM_STRUCT(6 parameters) defines job at hands.

static  char 	funnam[][FUNNAM_LEN + 1] = {
                           "f(t,e)/ none ",
                           " none /f(p)  ",
                           "f(t,e)/f(p,e)",
                           "f(t,e)/f(p,e)",
			   " none /f(p)  ",
			   "f(t,e)/f(p,e)",
			   "f(t,e)/f(p)  ",
			   "f(t,e)/ none ",
                           "f(t,e)/f(p,e)"};

Each family can have two curve to control. f(t) the independent of function(curve) is time; f(p) momentum; They may be event dependent - f(t,e) and 
f(p,e). This is falged by i1:i20 of DB table i3_pgm_pars. In it there are 2 int for each family for 't' table(curve,fuction) and 'p' table. 
Each word has 3 possible values: 0 -curve non-existing; 1 - existing;
-1: existing & event dependent.
for example the first par (-1,0) for anode table, f(t,e) / no 'p' table. When
you select table with the menubar it goes by this i3_pgm_pars.

Notes:
1. This is a job defining DB table(single rec) in I3
The first 6 are pars defined job at hand,PGM_STRUCT,
pgm_par1_r read the 6 pars in 
pgm_par1_update update when job is selected.
i1:i20 are used to define what kind of table: each pair is for a family.
The firsrt is about time table(independent variable is t);
the second is for momentum table(independent variable is p)
0 = none
1 = non-event dependent;
-1 = event dependent;
tgh represents the current table, either -1 or 1. 0 is out of question.
