HP48 programming: use values from stack in expression

Code:

\<< 1 GET                             @ Get unevaluated function from list

We don't need that step as EVAL takes care of the list:

'a'
'b'
{ + }
EVAL
'a+b'

Nice solution, by the way. I must admit I wasn't aware of neither ↑MATCH nor ↓MATCH.

I couldn't come up with a simple way to create something like this map based on 2 and 3:

Code:

{ { a 2 } { b 3 } }

But that allowed us to extract the repeated code and use DOLIST:

'a+b'
{ { a 2 } { b 3 } }
1
« ↑MATCH DROP »
DOLIST
'2+3'

Any suggestions on how to do that?

Or then rather use STREAM:

{ 'a+b' { a 2 } { b 3 } }
« ↑MATCH DROP »
STREAM
'2+3'
