Hello, I was wondering if anyone could help me understand this behaviour from my C64 mini:
Step 1: Save BASIC file using SAVE "FNAME",8,1. File save is good. Can re-load file and it is OK.
Step 2: Make changes to file.
Step 3: Save file using SAVE "FNAME",8,1. File save appears good, reports "Saving. Ready."
Step 5: Reload file.
Step 6: LIST file to see that changes have NOT been saved.
Result:
In effect, I can only save a file the first time, and the file save is therefore permanent.
Is this normal? I have the most recent firmware. This behaviour occurs using d64 images, the one created automatically by the C64 mini, as well as ones on my USB stick which were created with VICE.
Any suggestions or help is appreciated. I am expecting a C64 maxi to arrive shortly, I'm hoping this behaviour does not repeat itself on that machine. The work around, I suppose, is to keep saving files with new names and deleting the old ones.
I'm also wondering if this is how the C64 file system works, and that I probably skipped right into programming and missed some of the fundamentals. Your wise words and or ridicule are welcome.
SOLUTION:
After doing some research, found some extra commands that I have never seen before, some for renaming as well as deleting files. It worked!
Also found that the save and replace command comes with a bug! infogalactic.com/info/Commodore_DOS#The_save-with-replace_bug
Perhaps the real solution is to save a new file and delete the old one.
