First, here are some utility functions I use, including the key definition.

Code:

// BASE CONVERSION
KEY KA_3()
BEGIN
RETURN STRING(EVAL(MBase()));
END;

BEGIN
END;

// SETS mSEL GLOBAL VIA MENU SELECT
BEGIN
LOCAL mSEL;
mSEL:=0;
IF my≥220 AND my≤239 THEN
CASE
IF mx≥0 AND mx≤51 AND mTXT(1)>"" THEN
mSEL:=1;
END;
IF mx≥53 AND mx≤104 AND mTXT(2)>"" THEN
mSEL:=2;
END;
IF mx≥106 AND mx≤157 AND mTXT(3)>"" THEN
mSEL:=3;
END;
IF mx≥159 AND mx≤210 AND mTXT(4)>"" THEN
mSEL:=4;
END;
IF mx≥212 AND mx≤263 AND mTXT(5)>"" THEN
mSEL:=5;
END;
IF mx≥265 AND mx≤319 AND mTXT(6)>"" THEN
mSEL:=6;
END;
END; // CASE
RETURN mSEL;
END; // BEGIN

And here is the base conversion program itself.

Code:

EXPORT MBase()
BEGIN
LOCAL men,m,m1,mx,my,s;
// initialize
men:={"","BIN","OCT","DEC","HEX","EXIT"};

REPEAT // WAIT FOR A MOUSE CLICK
m:=WAIT(−1);
UNTIL (m(1)==3 OR m(1)==7);
mx:=m(2); my:=m(3);

IF (s==1  OR s==6) THEN RETURN END;

RETURN s:=SETBASE(Ans(1),s-1);

END; // BEGIN

Enjoy...

A couple of changes I made to my version allow the function MBase() to be also usable from the command line using passed parameter in both rpn and algebraic/textbook

In the base conversion program:

EXPORT MBase(in)
...
RETURN s:=SETBASE(in,s-1);

In the key definitions:
...
RETURN STRING(EVAL(MBase(Ans(1))));

It may be useful to some..
