Hi everybody!

I'm trying to use the SOLVE function of the 48 inside a program. 
It's easy to call the SOLVER menu with the command 30 MENU, but what
I'd like is precisely not see the SOLVER menu, but still use the SOLVE
command. Let me explain my poor self:

Suppose you have stored into EQ the equation:

                   A1*SIN(A2*X) = B1*COS(B2*X)

The SOLVER menu will show :

                A1  A2  X  B1  B2  EXPR=

and you can then enter values for A1,A2,B1,B2 (for example), and finally,
with SHIFT-LEFT and the menu key under X, "Solve for X".

I'd like my program to do just this, (storing values into variables,
and solve the equation), without asking anything to the user. 

Is there a way? Is it just plain and simple? Is there a SYSEVAL 
corresonding to each variable that you can solve?  

Is there anybody out there ?
