Input form in CAS programs

[compsystems]

The solution is to create again the input functions (HOME PRG) =(

the CAS should support DIALOG BOXES COMMANDS.

PHP Code:

#cas
cas_program():=
begin
  local var0;
  print( "***Started execution***" ); freeze; // Print on terminal Window
  // wait;
  var0:=cas_input("Title","a=","Help Line",8,3);
  print( var0 );
  freeze;
  var0:=(var0+x/y); // no pretty print on terminal Window 
  print( var0 );
  freeze;
  print( "***End execution***" ); freeze;
  return "Done";
end;
#end

// Rewriting again INPUT CMD
export cas_input(title_str,var_str,help_str,reset_val,init_val)
begin
  local input_var;
  input( input_var,title_str,var_str,help_str);
  return input_var;
end;
