Question about user mode key definitions.

Quote:I want to have this program run when I hit shift-base and change the input line to the appropriate base.

I miss this possibility, too. There will be reasons why such little things are or had been ignored. These little feature improve the usability very much.
My approach is something like that. (SoftMenu() is a menu-laucher that returns the softkey id) The additional two ENTERs seem to be unavoidable. Is it possible to take input from the command line instead of the stack? so purge a number from input and save ENTERing it to the stack.

Code:

SymbBaseMenu()
BEGIN
  LOCAL base_key := Base+1;
  LOCAL btn:=SoftMenu({{"bin","oct","dec","hex","","2Real"},base_key});

  CASE
    IF btn==1 THEN   Base:=0;IFTE(Entry==2,"INT_BIN","INT_BIN(Ans)"); END;   //2D  : Entry==0
    IF btn==2 THEN   Base:=1;IFTE(Entry==2,"INT_OCT","INT_OCT(Ans)"); END;
    IF btn==3 THEN   Base:=2;IFTE(Entry==2,"INT_DEC","INT_DEC(Ans)"); END;
    IF btn==4 THEN   Base:=3;IFTE(Entry==2,"INT_HEX","INT_HEX(Ans)"); END;
   // IF btn=5 THEN RETURN " R→B(1)"; END;
    IF btn=6 THEN RETURN " B→R()"; END;
    DEFAULT "";
  END;

EXPORT INT_HEX(X)
BEGIN
  LOCAL str;
  CASE
    IF TYPE(X)==0 THEN R→B(X,32,4); END;
    IF TYPE(X)==1 THEN SETBASE(X,4); END; //Base is already set to 3 
    IF TYPE(X)==2 THEN X:=UCase(X);  str:="#"+X+"h"; R→B(expr(str)); END;
//    IF TYPE(X)==2 THEN  str:="#"+X+"h"; R→B(approx(str)); END;
 //   IF TYPE(X)==2 THEN str:="#"+X+"h";  INT_HEX( CAS(str)); END;
    DEFAULT "";
   END;
 // R→B(X,32,4);
END;

Prime and I are a love-hate. I dig out the prime occasionally but only for playing with it. The productivity level is frustratingly low for me.
Maybe that is because I work as a hardware designer with lowest level firmware on the software side. Script-languages and HPPPL seem to be too complicated for me.
