Save RAM file to Flash Memory or UV Eprom file area in slot C (files to UV Eprom only in slot 3).
The routine does NOT handle automatical "deletion" of existing files that matches the filename (excl. device). This must be used by a call to OS_Epr, A=EP_Delete.
Should the actual process of blowing the file image fail, the new File Entry will be marked as deleted, if possible.
The screen is turned off while saving a file to flash file area that is in the same slot as the OZ ROM. During saving, no interference should happen from Blink, because the Blink reads the font bitmaps each 1/100 second:
...
By switching off the screen, the Blink doesn't read the font bit maps in OZ ROM, and the Flash chip can be in command mode without being disturbed
disturbed by the Blink.
Important:
INTEL I28Fxxxx series Flash chips require the 12V VPP pin in slot 3 to successfully blow data to the memory chip. If the Flash Eprom card is inserted in slot 1 or 2, this routine will report a programming failure. It is the responsibility of the application (before using this call) to evaluate the Flash Memory (using the OS_Fep, A=FEP_CDID call) and warn the user that an INTEL Flash Memory Card requires the Z88 slot 3 hardware, so this type of unnecessary error can be avoided. Equally, the application should evaluate that saving to a file that is on an UV Eprom only can be performed in slot 3. This routine will report failure if saving a file to slots 0, 1 or 2.
