Well, I wouldn't want to have to do this frequently, but it should have worked for
my purposes, except that at Step #12 below I got the DM42 error "State File Too New".
I'm guessing that I have to install a more recent version of something on my DM42,
which I'll do when my mind is a little fresher.
This is what I did:
1. Compose/save the matrix in file "mymatrix.tsv" in any text editor on my computer.
Columns are tab-delimited, rows are newline-delimited.
2. Save the state of my DM42 to file "OLD.f42" on my DM42.
3. Activate USB disk between my DM42 and my computer.
4. Copy file "OLD.f42" to my computer.
5. Launch Free42 (either "Decimal" or "Binary") on my computer.
6. Under menu "File / States...", Import file "OLD.f42".
7. In the text editor on my computer, copy file "mymatrix.tsv" to the copy/paste buffer.
8. Paste to Free42. Matrix in now in X on Free42.
9. Optional step: store X in some global variable in Free42.
10. Save the state of Free42 to file "NEW.f42" on my computer.
11. Copy file "NEW.f42" from computer to DM42 via USB disk.
12. Deactivate USB disk between computer and DM42.
13. Restore the state of my DM42 from file "NEW.f42".
The only change to the DM42 is the new matrix.
14. Cleanup: delete files "OLD.f42" & "NEW.f42" on DM42.
