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

It seems 'X' is undefined.
Try Mode, Flags, uncheck system flag 3

system flag 3 set --> "Function --> num" require that EVAL can result in a numerical value.
system flag 3 unset will allow for returning a symbolic
