HP50G Algebraic object multiply by variable

[royc]

Hi all,

I am new user of HP50G from HP48SX, and now having error when transferring program to HP50G, hop anyone can help to see what's wrong with the following program.

Example :

Work on HP48SX
<< 5 'X' * >> ---> '5*X'

HP50G
<< 5 'X' * >> ---> * Error: Undefined Name

Do I need to set some flags or mode?

Thank You
Roy
