Probs solving sys. of eqs. programatically.
How do I enter system of eqs using program, ex. PROG(sys_eqs,vars). I try variable as strings with/without curly/square brackets and nothing works. What I do wrong? Strings as arguments to programs used to work with CAS(),EXPR(). Does that changed in the latest beta? I use the latest beta firmware. In the PRGM in CAS I use solve or fsolve.

RE: Probs solving sys. of eqs. programatically.
Perhaps it is more convenient to work directly with objects.

For instance:
Code:
 #cas SZ_T1(eq_list) begin   local n:= size(eq_list);   local i, eq;    print ("");   print ("There is " + n + " objects");   for i from 1 to n do     eq:= eq_list[i];         print (i + ": " + eq);       end;     end; #end #cas SZ_T2(eq_list, var_list) begin   local n:= size(eq_list);   local i, eq;    print ("");   print ("There is " + n + " objects");   for i from 1 to n do     eq:= eq_list[i];         print (i + ": " + eq);       end;   print(" ");   print("Var list: ")   print(var_list);   print(" ");   print("Solution: ");   print(solve(eq_list,var_list));   end; #end

Examples:

SZ_T1( (2*x+3*y)=1, (x+y) = 2 )
SZ_T2([(2*x+3*y) = 1,(x+y) = 2],[x,y])
