? RPL/HP-48 - numerical S on a << >> integrand ?

Something like this :
0
1
<<X SIN X SQ - >>
'X'
S
where the legal way to integrate is :
0
1
'SIN(X)-SQ(X)'
'X'
S

a program gives sometimes more flexibility to build a function to integrate.

Try writing the program as a "user-defined function" which means storing the argument(s) in local variable(s) like this:

<< -> X << X SIN X SQ - >> >>
or
<< -> X 'SIN(X)-X^2' >>

RPL treats programs like that more like built-in functions when solving, graphing, and so on, so it might help here too.
