F/+HINT15
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
A=ISMSCH Search for key in index.
This call attempts to find the key in LINBUF in the index
that you specify. If no key is found, the index is still
"positioned", and you can use the "Get next key" and "Get
previous key" calls. A subsequent "Get next key" call
after a key was not found, returns the next highest value
key that is in the index.
On entry: Y contains the handle of the file.
LINBUF contains key to search for.
On exit: VS filing system error occurred; error
code in A.
CS key not found; internal error code in
A.
The file position is set.
REG1 contains pointer value of key, if
found.
A=ISMINS Insert key into index.
This call inserts the key in LINBUF into the index file.
On entry: Y contains the handle of the file.
LINBUF contains the key to insert.
REG1 contains pointer value to be
associated with the key.
On exit: The file position is reset.
VS filing system error occurred; error
code in A.
CS index is full; internal error code
in A.
A=ISMNXT Return next sequential key.
This call returns the pointer value of the next sequential
key, from the current file position.
On entry: Y contains the file handle.
On exit: VS filing system error occurred; error
code in A.
CS At end of file; internal error code
in A.
The file position is advanced by
one.
REG1 contains the pointer value
associated with the key.
A=ISMDEL Delete key from index.
This call deletes the specified key and associated pointer
value from the index file.
On entry: Y contains the file handle.
On exit: The file position is reset.
VS filing system error occurred; error
code in A.
CS Key not found; internal error code
in A.
REG1 contains the pointer value
associated with the key.
A=ISMCLS Close file.
This call closes the file; it both calls the filing system
to close the file, and closes the file within ISAM as well.
This is slightly different from the ISMOPN call, which
requires the filing system open call to be separate.
On entry: Y contains the file handle.
On exit: VS filing system error occurred; error
code in A.
A=ISMPRE Return previous key in index file.
This call returns the pointer value of the previous
sequential key in the index, from the current file position.
On entry: Y contains the file handle.
On exit: VS filing system error occurred; error
code in A.
CS Beginning of file; internal error
code in A.
The file position is moved back by
one.
REG1 contains the pointer value
associated with the key.
Printer Control Routines
The printer control routines handle the printer driver for the utility. A
printer driver must be loaded from ViewStore Command Mode before calling the
utility, or the default printer driver in the ROM is used.
Highlights can be sent to the printer driver from a utility, but there is no
provision for handling of the printer options byte or microspacing.
Highlights begin at 128 for highlight 1.
A utility can test the state of the printer by examining the location
PRNFLG. If bit 7 of PRNFLG is set, then the printer is switched on. If bit
6 of PRNFLG is set, then the printer is not actually on, but waiting: a
call to PRNON will switch on the printer.
The printer should be switched off before reporting errors.
ASKPRN Ask about printer.
PRNON Switch waiting printer on.
PRNOFF Switch printer off.
PSCOUTT Send character to printer/screen vector.
ASKPRN
This routine prompts the user with the question "Screen or Printer (S,P)?".
According to the response, bit 6 of PRNFLG is updated to indicate whether
the printer is waiting. If bit 6 is set, a subsequent call to PRNON by the
utility will switch on the printer.
On entry: No entry conditions.
On exit: PRNFLG Bit 6 set if printer is waiting; clear if
screen is to be used.
A,X,Y undefined.
