Adding/Editing Programs for the HP50G

[MattGreer]

I'm in the process of migrating from the 48GX to the 50G, or at least trying to get my little programs moved over. What I realize I've done is I used the connectivity kit to transfer the directories and CST out of my 48GX to my PC, which is done in ASCII. When I open them with a text editor, this is what I see (for example, an incomplete copy of a directory, top level of which is "CHE"):

Code:

%%HP: T(1)A(D)F(.);
DIR
  EQ1 'Q/A=hc*(Tw-T
)+˜*“*(Tw^4-T^4)'
  A '5.65895372234_
ft^2'
  Q '90000_Btu/h'
  U '112_Btu/(ft^2*
h*°F)'
  dT '142_°F'
  EQ { EQ1 HTX }
  HTX 'Q=U*A*dT'
  THERMO
    DIR
      EQULB
        DIR
          EQ '
1.06084841536E-2=4*

(Forgive the formatting, that's just how it comes out.)

When I copy it to the SD card and then insert the SD card into my 50G and then transfer it over to the HOME directory, what I transferred comes out as a string. Not a directory with subdirectories, equations, programs, etc. as it was on the 48GX.

So here are my questions:

1. Obviously I have to transfer these things from the 48GX in binary for them to work correctly in the 50G, right?
2. I'd like to be able to edit these things on my computer. How can I transfer over, edit them, and then transfer them back?
