I understand that you intend for those lines to be comments, but the 50g doesn't recognize "//" as a comment indicator. As a result, the 50g will attempt to interpret those lines as RPL code. It's possible that HPUserEdit doesn't pass those lines along to the calculator, though. I'm not familiar with HPUserEdit, so I can't say with certainty how it treats those lines.

Many of those ?s are actually supposed to be single quotes, such as in these lines:

Code:

xf ?xi? STO F ?T? STO+
xd ?xi? STO F ?T? STO+

They should actually be coded as follows:

Code:

xf 'xi' STO F 'T' STO+
xd 'xi' STO F 'T' STO+

There's other places where ?s show up, though, and it's apparent that they aren't supposed to be single quotes. Your program will have syntax errors until you remove all the ?s and replace them with the appropriate substitutions.

Generally speaking, you're better off when you use the HP "tri-graphs" in your code instead of using special characters. So instead of using "«" and "»", you would use "\<<" and "\>>". Also in your code, you have:

Code:

OBJ-> DROP

...which will definitely create an error. You should use

Code:

OBJ\-> DROP

instead.

Likewise for

Code:

->

you would use

Code:

\->

The tri-graphs are converted to single characters as appropriate when the 50g compiles the program.
