Can anyone advise on how to set the program (or file?) version number
in either C68 or assembler?
And then, how does one read it back in SBASIC?
SET_FVERS in the level 2 drivers sets it in SBASIC.
You can also use IOF.VERS (Trap #3, D0=$4E) on Level 2 device drivers - alas this
clashes with another trap call on the THOR XVI - hmm - the standards were dropping
there
IOF.SHDR (trap #3 D0=$46) does not appear to be able to do it as it can only write the
first 14 bytes of the header. Is this still valid??
FVERS reads it: PRINT FVERS(\ram1_test)
However, these commands are not present on non level-2 drivers.
There are plenty of PD BASIC extensions to read the 64 byte file header - the version
is stored at offset 5758.
BTW - you might also want to look at the details for the file access key (byte 5)
which was used by Toolkit III and the System Toolkit to say if a file was hidden (bit
6) / read-only (bit 7), or even the number of a specific user (0 to 63 in bits 0 to
5). If a value of 0 was used, anyone could access the file. Otherwise you had to
have the same user number to see or use the file. User 63 was used for password
protected files.
